Abstract Details

Purpose:

To evaluate the postoperative asphericity after transepithelial photorefractive keratectomy (PRK) with Schwind Amaris (SA) laser

Setting:

Pacific Laser Eye Centre, Vancouver, BC, Canada

Methods:

Retrospective case series . The outcomes of myopic transepithelial PRK with SA have evaluated at 3 month follow-up in over 100 eyes and divided into moderate (up to -6D) and high myopia (from -6D). In all cases standard examinations, pre- and postoperative corneal-wavefront analysis (Schwind Sirius) were performed.

Results:

At 3 months postoperatively the moderate myopia group (n=111) maintained or slightly improved negative asphericity compared to preoperative values (Q=-0.05±0.15 pre-op vs. -0.13±0.23 postop, p>0.05). At 3 months postoperatively the high myopia group (n=44) were more oblate compared to preoperative values (Q=-0.10±0.15 pre-op vs. +0.58±0.69 postop, p<0.01). The difference between groups was significant (p<0.01).

Conclusions:

Transepithelial PRK with Schwind Amaris maintains preoperative corneal asphericity for low to moderate myopic corrections (up to -6D). This may provide advantages in the quality of vision or in the onset of presbyopic symptoms in post refractive surgery myopic population.
