Monovision scleral lenses
We saw a 66 year old male with a history of monovision LASIK OU 20 years ago. In the last few years, he began showing signs of ectasia OU and found about 9D of astigmatism. This is a very high amount of astigmatism! For reference, most soft contact lenses can only go up to -2.75D. His right eye (distance) was 20/30 far and left eye (near) was OS 20/ 20 at near but describes ghosting and shadowing. Both eyes, he was seeing 20/25 distance. He felt modest about his vision and was functioning well in his daily activities but wanted to see if he could see better.
With a diagnostic lens, he noticed a significant improvement in his vision and was eager to proceed. He was fit with the Latitude scleral lenses and kept in monovision. This goes to show that the number on the chart (ie 20/20) may not always correlate to the quality of vision. Even if a patient can see the letters on the chart, the letters may still have ghosting or appear doubled. This can be very debilitating for patients.
We saw him a week after his dispensing his new lenses and was thrilled to see how well he was doing with the new lenses! His vision was OD 20/ 20 far, OS 20/ 25+ near and OU 20/ 20 distance. Although he felt that his vision before the lenses were decent, he was most surprised at how much more he was able to see in his daily life. He described noticing the new details of the distant mountains during his daily drives to work.
Thank you Dr. Jenny Wong for your excellent care for this patient and for this update!
We love helping patients like these achieve vision that they haven’t seen in years!
Thank you Dr. Paul Casey for this fun case!
