CUSTOM SCLERAL LENS

Patient Referred To Us For Corneal Inflammatory Condition

Thank you Dr. Stafeeva for your kind referral to our office!

A 59 year old patient was kindly referred to us from her corneal specialist, Dr. Stafeeva.

This patient had a corneal inflammatory condition of unknown etiology and has been managed with many eye drops including antibiotics, steroids, and other eye drops.

Although the inflammation has resolved, she is left with a very large corneal scar with pannus and neovascularization.

You can see from the topography images, the K max is over 60 diopters in a small central island. The scleral topography images show some large amount of scleral toricity and irregularity.

Her habitual glasses are about a +4.50 in each eye and she can see 20/20 in the right eye and 20/200 in the left eye. When we don't know the vision potential of a patient, we always trial a diagnostic lens. With a diagnostic scleral lens and a +1.75 over-refraction, she was able to achieve 20/20 vision in the left eye! She was thrilled with the improvement in her vision.

Due to the large amount of irregularity, we highly recommended a custom scleral lens such as the Latitude scleral lens or the EyePrint lens. She is going to discuss with her husband and let us know which lens she wants to proceed with.

Also, we may need to fit her into a soft contact lens for the OD to account for the anisometropia, but we will determine that at the dispense.

She will continue her primary eye care with Dr. Ochiltree and any cornea care with Dr. Stafeeva.

This patient suffers from poor vision as a result of prior eye surgery. She had radial keratotomy surgery (also known as RK surgery) in the early 1990’s. This surgery was a popular option for patients looking to eliminate their glasses or contact lenses.

Watch EyePrint Demo

RK surgery involved the surgeon making small cuts onto the cornea in a spoke-like pattern, hence the name “radial.” Making the incisions allowed the cornea to reshape and become flatter in the center. This changed the shape of the eye, which reduced the need for glasses or contact lenses.

Most RK patients saw well for many years, but as time has progressed, there have been many issues.

RK scarring in the cornea

RK patients suffer from blurry vision, distorted vision, ghosted vision, shadow-y vision, double vision, and other visual complications.

This patient also has a corneal transplant. This was due to the enormous amount of scar tissue in the center of the cornea.

Due to her very irregular cornea, we decided to fit her into an EyePrint Prosthetic.

Eyeprint+checking+for+tackiness

The Eyeprint procedure is painless and take less than 3 minutes

Step-by-step instructions:

  • First, the tip is placed at the edge of the impression material and locked into place.

  • Next the trigger is squeezed, which allows 2 separate materials to combine in the chamber of the tip.

  • The mixed materials are placed into a small plastic tray.

  • We wait for 40 seconds for the material to set.

  • Then, the patient looks at their fixation target.

  • Quickly, the impression is inserted under the upper eyelid and then the lower eyelid. This is the most important part. You must get the lids out of the way.

  • Let go.

  • The patient continues to look at their fixation target for about 90 more seconds so the material can set.

  • Then, the impression is removed.

  • After, we proceed with a diagnostic scleral lens fitting to determine what power to add into the EyePrint.

Watch EyePrint Pro Demo

After several impressions are obtained, we send them to the EyePrint lab in Colorado. Next, the lab uses a 3-D scanner and captures over 3 million data points using information from the impression. This information is then used to design a perfectly custom scleral lens. The lens is then fabricated in the lab and then shipped to us for dispensing.

When the EyePrint arrives, we will call the patient and schedule her for a scleral lens dispense.

We were able to achieve 20/20 vision with the EyePrint with this patient. Looking forward to seeing how her next visits go!

Next: Does Insurance Cover Scleral Lenses?

What Are Custom Scleral Lenses?

The sMap is such a cool instrument, and it tells us a lot of information.

Normal topographers map the corneal surface only, and give little (if any) data about the shape of the sclera. Since scleral lenses rest on the white part of the eye (the sclera), it makes sense that a scleral topographer could help improve our scleral lens fits. Scleral topographers are expensive, which is why most eye doctors do not offer this technology in their office. It would only make sense for clinics that are fitting scleral lenses at a high level to invest in this equipment.

This particular patient has severe keratoconus in the right eye (K max of over 70 diopters). He complains that a traditional scleral lens does not fit his eye perfectly and he has issues with redness and irritation. With the slit lamp, we observe a small area of elevation inferiorly and a slight area of increased elevation nasally. The nasal elevation is a result of a small pinguecula.

RLL+(2)

A small area of elevation is seen on the sclera (white part of the eye) . This was easily detected with the sMap.

The sMap images take 3 D images of all areas of the eye, and the information is used to create a custom fit scleral lens. We instill a drop of sodium fluorescein and have the patient look up, down, and straight ahead. Then, the sMap software stitches the images together to give us a 3D image of the shape of the sclera.

Notice how the 3:00 and 6:00 position are slightly "warmer" colors compared the the rest of the sclera. This is due to the elevation of the pinguecula nasally and the small area of elevation inferiorly.

Notice the 3:00 position and the 6:00 position have more of a teal and yellow color compared to the other colors on the map.

This information will be used to create a custom scleral lens, which should vault over those areas perfectly. This results in an extremely accurate scleral lens fit.

So grateful to have this special technology in our office!

Damage to Eye from a Burning Building

Super interesting case from Dr. Schorr from New Eyes!

We saw a 19 year old boy for a consultation today. He suffered a trauma from going into a burning building and when he opened the door, the door flew open and the padlock hit him in the right eye. According to the patient, he left the burning building but then his boss told him to go back in. When he went back in, he opened the door, and (probably due to backdraft), the door slammed into the right side of his face and the padlock went right into his eye. He was a child when this all happened.

Cornea+trauma+OD.+and+corneal+scar+jpg

Large, dense corneal scar which goes right through the center of his eye.

He had a globe perforation to his eye that had to be repaired quickly.

His crystalline lens could not be saved, so he is aphakic in that eye. He has severe corneal scarring. There is also a dense amount of scar tissue that attaches the posterior cornea to the anterior iris. You can see in the OCT image below that the back side of the cornea attaches to the front side of the iris.

He also has an artificial pupil and iris defect both nasally and inferior nasal.

His main goal of today’s visit was to see if a specialty lens could improve his vision. He sees count fingers at 4 feet and complains of diplopia in the right eye.

When I looked at his eye, I had little hope that any vision improvement would be possible, due to the severe scar tissue and lack of a normal entrance pupil.

We tried on a diagnostic Europa scleral lens to see if any vision improvement was possible and with a +8.00 over refraction, he could achieve 20/50 and he stated his double vision was gone.

Due to the ocular condition, he must be eccentrically viewing out of his artificial pupil inferiorly. We are going to attempt a scleral lens for him to see if it helps improve his vision, diplopia and balance. Stay tuned for updates!

sMap+OD (1)

The sMap takes a series of 3D images to help create a custom scleral lens

Scleral topographers are able to map the white part of the eye, called the sclera. This is important because this is the area that the scleral lens lands on. It would make sense that using a scleral topographer would give us important information about the shape of the entire eye, not just the cornea.

This particular patient has severe keratoconus in the right eye (K max of over 70 diopters). He complains that a traditional scleral lens does not fit his eye perfectly and he has issues with redness and irritation. With the slit lamp, we observe a small area of elevation inferiorly and a slight area of increased elevation nasally. The nasal elevation is a result of a small pinguecula.

This is due to the elevation of the pinguecula nasally and the small area of elevation inferiorly.

The sMap generates a scleral topography to show us areas of elevation

This information will be used to create a custom scleral lens, which should vault over those areas perfectly. This results in an extremely accurate scleral lens fit.

Good candidates for custom scleral lenses include patients with extreme eye conditions, such as severe keratoconus, graft-vs-host disease, sjogren’s syndrome, extreme dry eye, glaucoma patients, and patients who have difficulty with their current scleral lenses.

We have been able to help thousands of scleral lens patients with this incredible technology.

So grateful to have this special technology in our office! Book an appointment with our office to see if you would be a good candidate for the sMap!

Keratoconus patient sees clearly for the first time in years!

Keratoconus patients are so rewarding!

A 22 year old female was referred to us from Dr. Wellish. She has keratoconus in both eyes. She had corneal crosslinking in the left eye 3 months ago. She will be getting corneal crosslinking in the right eye next month.

She complains of blurry vision, distorted vision, and fluctuating vision. She states her left eye has been a lazy eye for quite some time and she remembers that her vision in that eye was able to achieve 20/40 at one point.

With glasses, she could achieve 20/80 vision in the right eye and 20/200 in the left eye.

After reviewing all of the options, she decided to proceed with the Latitude custom scleral lens. We took 3D images of the left eye and used a diagnostic scleral lens to determine her vision. To our surprise, she was able to achieve 20/20 vision!

We built a trial frame for her and let her roam around the office so she could get a sense of what her new vision would be! She was thrilled and her mom was thrilled too!

Such a fun case, we can’t wait to see her back for her dispense.

Keratoconus Patient fit into custom scleral lens

Thank you Dr. Dadej for your kind referral of your keratoconus patient to our office!

This young man was diagnosed with keratoconus about 5 years ago and was fit into hybrid lenses. The hybrid lenses were not comfortable, so he was switched into scleral lenses a few years ago. Hybrid contact lenses are a lens type that combines a gas permeable contact lens with a soft contact lens. The middle of a hybrid lens is made with a gas permeable lens which is then surrounded by a soft contact lens skirt. Hybrid lenses are used for a lot of different patients. The Ultrahealth hybrid lens is intended for Keratoconus patients. Many patients do well with hybrid lenses.

This patient wore scleral lenses successfully for years.

Dr. Dadej did a great job fitting him into new scleral lenses this year, but because of the severity of his keratoconus, the lenses were still not fitting just right. He developed a corneal scar on the right eye and the left eye, and Dr. Dadej referred him to me right away to help prevent a central cornea scar. Central corneal scars can cause significant vision impairment, and may require a corneal transplant if severe enough.

After discussing the different contact lens options, we decided on the Latitude custom scleral lens. We took 3 D images of both eyes and sent the images to Visionary Optics to help design and fabricate Latitude custom scleral lenses for him. With a diagnostic Europa lens and over-refraction, he achieved 20/20 vision in each eye and he was very happy. I am excited for his dispense!

Thank you again Dr. Dadej for thinking of us to help this special patient!

Custom Scleral Lenses Help Physician to See Better

We had the pleasure of seeing our patient back for a Latitude custom scleral lens dispense today.

This patient had LASIK surgery years ago, and he had monovision correction. This means that one eye is corrected for distance and one eye is corrected for near. In his case, the right eye was corrected for distance and the left eye was corrected for near.

He was successful for many years, and he was able to function glasses-free.

He was seen by his primary care ophthalmologist, Dr. Paul Casey, for his annual exam a few months ago. Dr. Casey had discovered that this patient developed some highly irregular astigmatism in both eyes, likely due to the LASIK surgery.

Even though the vision was still quite good (around 20/25 both far and near), Dr. Casey wanted him to see me for an evaluation due to a desire to improve vision quality.

This patient saw us for a consultation in February 2021 and he stated that although he saw clearly, some of the images were a bit distorted, and he had a bit of ghosting at night.

When we viewed his topography, we could see why the vision became more distorted at night time. As the pupil increases in size, he starts to see into the midperipheral cornea, which is more distorted in shape.

We also found that he had more than 7 diopters of cylinder in the left eye. Both eyes exhibited irregular topography images.

Dr. Casey has been repeating the topography scans every 3 months and for the past year, the patient has been completely stable.

We decided to put a diagnostic scleral lens on for fun, just to see if it would improve his vision.

With the Europa scleral lens on each eye and an over-refraction, the patient could see 20/20 in each eye and, most importantly, he noticed a huge improvement in the overall QUALITY of vision. This is important because even if someone can technically see 20/20, that does not mean that they have good vision. If the vision is distorted, blurred, has haloes, or glare, it can be very disturbing to the patient. Since he was so happy with the improvement in the quality of vision, we decided to proceed with a scleral lens fitting.

Due to the highly irregular curvature of each cornea, we decided to proceed with a custom scleral lens design, called the Latitude scleral lens. We took 3D images of the eye with the sMap machine, and the laboratory designed a pair of custom scleral lenses for him.

At the dispense, visit, he noticed the vision was very good. He was seeing 20/20 at far and 20/20 at near. The OCT images showed that there was a bit of shallow clearance, but we dispensed the lenses and followed up with him one week later.

At the one week follow up, Dr. Wong noticed that the clearance was a bit too shallow superiorly. Although the patient loved his new vision, we had to re-design his lenses for safety purposes. He also mentioned that when he removes his lenses, they are really stuck on his eye and they feel like champagne bottles popping off his eye. This is not normal and usually means the fit needs to be modified.

Today, we saw him for another Latitude dispense. The lab made some minor adjustments to the lenses to increase the fluid layer underneath the scleral lenses to help improve the fit and help with lens removal.

He mentioned the new lenses were even more comfortable than the old lenses, and we were very happy that the new lenses showed more central and midperipheral clearance.

We feel very honored to have worked with such an amazing patient! Scleral lenses are so rewarding, and it is an honor to be a part of their journey to better vision.

Keratoconus patient fit into custom scleral lens

public (2)

A nice patient was seen today for a specialty contact lens consultation. He was diagnosed with keratoconus 2 years ago at the age of 34 years old. He wore focus daily soft lenses for years, but 2 years ago, he noticed some changes in his vision, which led his optometrist to perform a topography. The topography revealed keratoconus OD>OS.

He gets Pentacam images every 3 months, and his corneas are both very stable, which is why he has not had corneal cross linking.

He was then fit into different scleral lenses which didn’t feel right (comfort wise) and the most recent lenses made him feel “wonky.” His main complaint was that his eyes suffer from ghosting, especially at night. With the current scleral lens, the ghosting is still apparent sometimes when the lens decenters.

We decided to perform a few tests and see for ourselves.

His scleral topography is interesting because the more elevated areas are at more of an oblique axis, which might explain why the traditional scleral lenses did not fit perfectly. With a diagnostic Europa lens, he still noticed some ghosting and accepted cylinder in his over-refraction. I performed an over topography to check for flexure, and it appears that it is possible that the lens shape could be contributing to the residual cylinder.

After analyzing all of the image, Sabrina from Visionary Optics helped me design a new lens for him. We decided to keep any cylinder out of the first pair, because that will make things more challenging if we need to alter the fit or Rx later. We are going to increase the optic zone to 9.0 mm to help with the ghosting as well. I am hoping that by order the custom Latitude scleral lens, the lens will center much better and will help to decrease or eliminate the ghosting.

Looking forward to his dispense. Thanks to the sMap team for their help with this fun case!
