Abstract

Abstract: : Purpose: To evaluate the early postoperative visual outcomes after photorefractive keratectomy (PRK) compared to laser in situ keratomileusis (LASIK). Methods: Retrospective analysis of 22 eyes from 11 consecutive patients that underwent PRK and 22 preoperative refraction–matched eyes from 20 patients undergoing LASIK, all with the Wavelight Allegretto Wave excimer laser. Postoperative outcomes compared included uncorrected visual acuity (UCVA), best spectacle–corrected visual acuity (BSCVA), and spherical equivalent refractions (SE). Results: Average preoperative SE was –4.96 D for PRK cases and –4.90 D for LASIK cases (range –2.25 to –7.88). Average age was 33.1 years (24–49 y) for PRK cases and 35.5 years (22–55y) for LASIK cases. Average 2 week UCVA was 20/26.5 (range 20/15 to 20/70) for PRK cases, and 20/24.8 (range 20/15 to 20/70) for LASIK cases (p = 0.63). At two weeks, 40.9% achieved 20/20 or better UCVA after PRK and 72.7% achieved 20/20 or better UCVA after LASIK (p = 0.06), while 90.9% achieved 20/40 or better UCVA after PRK and 90.1% achieved 20/40 or better UCVA after LASIK (p = 1.0). Average 2 week BSCVA was 20/21.8 (range 20/15 to 20/40) for PRK cases, and 20/19.8 (range 20/15 to 20/30) for LASIK cases (p = 0.11). At two weeks, 68.2% achieved 20/20 or better BSCVA and 95.5% achieved 20/40 or better BSCVA after PRK, while 95.4% achieved 20/20 or better UCVA and 100% achieved 20/40 or better UCVA after LASIK. Average 2 week SE was 0.125 D (range –1.25 to 1.5) after PRK and –0.13 D (range –0.88 to 1.75) after LASIK (p = 0.23). Three–month data will be analyzed and presented. Conclusions: PRK yielded comparable early visual acuity and postoperative refractive outcomes to LASIK after treatment with the Wavelight Allegretto Wave excimer laser.
