Abstract
Purpose :
This prospective study compared clinical outcomes and quality of vision in physicians undergoing LASIK and PRK.
Methods :
Fourteen physicians undergoing LASIK and seven physicians undergoing PRK were evaluated. Visual acuity (VA) and spherical equivalent (S.E.) were compared before treatment and at year 1. Wavefront aberrometry was used to measure for higher order aberrations (coma, trefoil, spherical aberration) in all patients. Validated questionnaires were used to assess visual symptoms and the Ocular Surface Disease Index (OSDI).
Results :
VA improved from baseline in both the LASIK group (P<0.001) and the PRK group (P<0.001). Final UCVA was logMAR -0.03±0.06 for the LASIK group and logMAR -0.01±0.11 for the PRK group, this was similar between the groups (P=0.44). Mean S.E. at year 1 was -0.04±0.18D for the LASIK group and -0.04±0.40D for the PRK group, this was similar between the groups (P=0.92). There was no statistically significant difference in coma, trefoil, or spherical aberration between the groups. PRK subjects reported less glare and fewer double images compared to baseline. OSDI scores were lower in the LASIK group compared to the PRK group (P=0.0497).
Conclusions :
Physicians who underwent LASIK and PRK had similar refractive outcomes and higher-order aberrations at 1 year. Quality of vision was similar among both groups. Key differences were improvement in glare and double images from baseline after PRK and lower OSDI scores after LASIK.
