Comparing laser in situ keratomileusis and photorefractive keratectomy in different eyes of the same patient.

PURPOSE To compare visual outcome of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) in fellow eyes. VS LASIK

METHODS  50 myopic patients who underwent LASIK in one eye and PRK in the fellow eye.  DECISION FOR PRK: when we couldn't do LASIK: - I-S ratio greater than Residual stromal bed ≤ 250μ - CCT ≤ 470μ  Minimum F/U 6 months. VS LASIK

RESULTS PREOP I-S 0.73 D 1.04 D PRK LASIKP SEQ -4.13± 2.06 D -4.75±2.80 D BCVA VS LASIK

RESULTS POSTOP UCVA 0.98± ± PRK LASIKP SEQ ± 0.32D -0.07± 0.50 D BCVA 1.04± ± Safety Index 1.05± ± Efficacy Index 0.98± ± VS LASIK

RESULTS VS LASIK POSTOPERATIVE UCVA Postoperative UCVA  ≥20/40; 100% in LASIK, 92% in PRK  ≥20/20;74% in LASIK, 66% in PRK

RESULTS The BCVA  Improved 14 (28.0%) and in 19 (38.0%) patients in LASIK and PRK  Unchanged 31(62.0%) and in 26 (52.0%) patients in LASIK and PRK  Decreased 5 (10.0%) and in 5 (10.0%) patients in LASIK and in PRK % % % % % % LASIK PRK VS LASIK

RESULTS  Change in BCVA pre- post operatively  Postoperative SEQ LASIKPRK preoperative postoperative LASIK PRK 44 88% 5 10% 1 2% 44 88% 5 10% 1 2% VS LASIK

CONCLUSION There is no difference in the outcome of LASIK and PRK in the fellow eye. VS LASIK
