Abstract Details

Purpose:

To evaluate the outcome of photorefractive keratotomy for treating patients with high myopia and myopic astigmatism

Setting:

Care vision, Inc., Tel-Aviv, Israel. Tel Aviv Sourasky Medical center, Tel Aviv, Israel.

Methods:

Retrospective analysis of 492 eyes with high myopia (spherical equivalent <=-6D) who underwent photorefractive keratotomy (PRK) without MMC using WaveLight® EX500 Excimer Laser between January 2013 to July 2013 where analyzed for outcome and complications rate.

Results:

Two hundred sixty nine (54.7%) were men. Mean age was 25.7 ± 6.52 years. Mean follow up was 80.34 ( 4-309 ) days. Mean Subjective spherical equivalence before and after surgery were -7.3D ± 1.71D and 0.42D ± 0.63D respectively. Pre-operative mean Central Corneal Thickness (CCT) was 523.75 micron and was significantly reduced to 389.41 micron post-operatively (P<0.001). Mean uncorrected visual acuity (UCVA) Pre-operative and post operative was 1.96 LogMAR ± 0.19 and 0.1 LogMAR ± 0.14 respectively. Mean best corrected visual acuity (BCVA) was 0.07 LogMAR ± 0.07 and 0.06 LogMAR ± 0.07 respectively. At the last follow up 60.5% of the patients were within ±0.50D from emmetropia and 87.1% were within ±1.00D from emmetropia. Corneal haze was documented in 19 eyes (3.9%).

Conclusions:

Photorefractive keratectomy among high myopic patients may be a safe and effective procedure with low complication rate. FINANCIAL INTEREST: NONE
