dc.description.abstractProcedures to reshape the cornea to correct refractive errors have been a longstanding and fast-evolving area of interest for centuries. As recent advances in excimer laser technology allow keratorefractive treatments to deliver precise treatments with fewer associated risks and complications, the popularity of modern refractive procedures continues to grow at unprecedented rates. For this reason, it is imperative to continue correlating patient characteristics to outcomes so that refractive surgeons can more accurately foresee the results of the selected procedure. This study examined the outcomes of refractive surgeries at a full-scope ophthalmology clinic from January 2011 to November 2011. The main objectives of th is study were to determine the differences between the outcomes of LASIK vs. LASEK, Custom vs. Traditional treatment plans, myopic vs. hyperopic patients and MMC exposure vs. no MMC exposure (LASEK only). More importantly, the data was scrutinized to determine whether or not any of these treatments and/or patient characteristics correlated with poor visual outcomes or the need for an enhancement. Of the 590 myopic eyes treated with Custom LASIK, 90.85% (n=536 eyes) had UDVA of 20/20 or better, 96.10% (n=567 eyes) had UDVA of 20/25 or better and 99.32% (n=586 eyes) had UDVA of 20/40 or better. Of the 170 myopic eyes treated with Custom LASEK, 70.59% (n=120 eyes) had a UDVA of 20/20 or better, 82.94% (n=141 eyes) had a UDVA of 20/25 or better and 96.47% (n=164 eyes) had a UDVA of 20/40 or better. Of the 45 hyperopic eyes that were treated with Traditional LASIK, 44.44% (n=20 eyes) had postoperative UDVA of 20/20 or better, 62.22% (n=28 eyes) had postoperative UDVA of 20/25 or better and 82.22% (n=37 eyes) had postoperative UDVA of 20/40 or better. Of the 536 eyes receiving LASIK, 91.42% (n=490 eyes) had an UDVA of 20/20 or better, 96.46% (n=517 eyes) had an UDVA of 20/25 or better and 99.44% (n=533 eyes) had an UDVA of 20/40 or better. Of the 146 low or moderately myopic eyes receiving Custom LASEK, 74.65% (n=106 eyes) had an UDVA of 20/20 or better, 86.62% (n=123 eyes) had an UDVA of 20/25 or better and 96.48% (n=137 eyes) had an UDVA of 20/40 or better. Of the 54 highly myopic eyes treated with Custom LASIK, 85.19% (n=46 eyes) had an UDVA of 20/20 or better, 92.59% (n=50 eyes) had an UDVA of 20/25 or better, and 98.15% (n=53 eyes) had an UDVA of 20/40 or better. Of the 28 highly myopic eyes treated with Custom LASEK, 53.57% (n=15 eyes) had an UDVA of 20/20 or better, 64.29% (n=18 eyes) had an UDVA of 20/25 or better, and 96.43% (n=27 eyes) had an UDVA of 20/40 or better. An analysis of these data yields significantly greater percentages of myopic (low, moderate and high) eyes achieving 20/20 or better after treatment by Custom LASIK versus Custom LASEK. The data suggested no correlations between poor visual outcomes and/or the need for an enhancement treatment and intraoperative complications, magnitude of ametropia, pupil size, age, treatment type, and treatment plan. All of the LASEK patients who underwent an enhancement treatment were exposed to MMC during their original procedure. Hyperopic patients displayed significantly reduced visual outcomes than comparable myopic treatments. Future studies should investigate similar preoperative characteristics and attempt to correlate them to results to improve predictability and, thus, visual outcomes.en_US
