Abstract Details



Purpose:

To evaluate the safety and efficacy of performing hyperopic PRK over an opaque, intracorneal inlay to improve uncorrected near visual acuity and visual satisfaction by inducing myopia in the eye.

Setting:

Private ophthalmology practice in Indianapolis, IN

Methods:

A total of 7 patients who had previously received an unilateral, intracorneal inlay to treat presbyopia developed consecutive hyperopia and were less satisfied with their unaided near visual acuity and visual function. All 7 patients had trials of soft contact lenses to induce varying degrees of myopia and all patients desired a permanent myopic change in their vision. All 7 patients elected to receive hyperopic PRK over their opaque, intracorneal inlay to induce varying degrees of myopia to improve their visual satisfaction and unaided near visual acuity. Pre-PRK and post-PRK, all patients had the following information recorded - UCDVA, UCNVA, topography, corneal appearance, and visual satisfaction. The patients were followed for 200 to 452 days (mean 432 days).

Results:

There were no complications noted at any time. 100% of patients had a healing pattern typical for hyperopic PRK and became myopic. 100% of patients improved their UCNVA with the increase ranging from 2-6 Snellen lines, mean 4 line increase in UCNVA. The PRK's effect on the UCDVA was from 5 lines of UCDVA lost to 3 lines gained, mean 1 line lost. 100% of patients reported an improvement their visual satisfaction.

Conclusions:

Hyperopic PRK over an opaque corneal inlay appears to be safe and effective to treat consecutive hyperopia and improve unaided near visual acuity and visual satisfaction while minimally decreasing binocular UCDVA.
