Abstract Details

Purpose:

To compare the safety, efficacy, predictability, refractive outcome, contrast sensitivity and spherical aberrations in eyes undergone SMILE & PRK over one year follow-up period

Setting:

Prasad Netralaya Super Speciality Eye Hospital, India

Methods:

A retrospective study was carried out to compare the visual outcome of 50 eyes which underwent PRK and 50 eyes which underwent SMILE at follow-up periods of 1, 3, 6 and 12 months. Pre & postoperative uncorrected visual acuity, best corrected visual acuity, contrast sensitivity and spherical aberrations were compared.

Results:

100% & 95% of the eyes which underwent SMILE and PRK respectively achieved postoperative refraction within 0.5D of the intended target refraction. Better contrast sensitivity was found in SMILE group as compared to PRK group. Post-operative spherical aberrations were found to be more in PRK group (0.4168) as compared to SMILE group (0.3720).

Conclusions:

SMILE is better in terms of refractive accuracy and quality of vision as compared to PRK.
