To assess the subjective satisfaction, visual disturbances, and dry eye symptoms following Phorcides planned Contoura topography-guided LASIK. This was a single site, single arm, prospective study of patient reported outcomes after bilateral Phorcides planned Contoura topography-guided LASIK. Preoperative and postoperative data were collected for responses on the Patient-Reported Outcomes with LASIK Symptoms and Satisfaction (PROWL-SS) questionnaire (a lower score represented a worse outcome), Ocular Surface Disease Index (OSDI) questionnaire (a higher score represented a worse outcome), refraction, and visual acuity. Linear mixed effect models were used to compare preoperative and postoperative scores on the PROWL-SS for satisfaction, and the frequency, bothersomeness, and visual impact of glare, halo, starbursts, and double images. A total of 50 subjects completed the study. Mean age was 29.3 ± 5.0 years (range 20 to 39 years). The mean 3-month postoperative satisfaction score was 53.2 higher than the mean preoperative score (p <0.0001). Mean 3-month postoperative scores were 7.4, 13.7, 18.0, and 29.2 higher postoperatively compared to preoperatively for double image, glare, halo, and starburst, respectively. All differences were significant (p <0.0001) with the exception of double image. Mean score on the OSDI questionnaire was 27.0 ± 22.4 preoperatively, compared to 7.5 ± 6.7 at 3 months postoperatively (p <0.0001). Postoperatively, 97% of eyes (90/100) had MRSE within ± 0.5 D and postoperative residual astigmatism was ≤ 0.5 D in 96% of eyes (96/100). Postoperative UDVA was 20/20 or better in 98% (98/100) of eyes, 20/16 or better in 81% (81/100) of eyes, and 20/12.5 or better in 31% (31/100) of eyes. The results of this study suggest improved patient reported satisfaction, reduced dry eye symptoms, and overall decrease in visual disturbances at 3 months following Phorcides planned Contoura LASIK.
