Objective: To evaluate the clinical results in patients with myopia up to -6 dioptres(D) after refraction surgery, evaluate their stability and compare photorefractivekeratectomy (PRK) and laser in situ keratomileusis (LASIK).Material and methods: The authors evaluated before and after surgery therefraction values in patients with myopia up to -6 D operated in 1999 and 2000.The patients were subjected to standard examination before operation, one week,1, 3, 6 and 12 months after operation. The group comprised a total of 542 eyes, 452PRK eyes and 90 LASIK eyes.Results: After PRK surgery the mean spherical refraction after one year was -0.35± 0.71 D, the mean astigmatism -0.63 ± 0.38 D, UCVA 0.90 ± 0.19, BCVA 0.98 ± 0.11.After LASIK surgery after one year the mean spherical refraction was -0.10 ± 0.81D, the mean astigmatism -1.05 ± 0.65 D, UCVA 0.80 ± 0.24, BCVA 0.86 ± 0.21.Conclusion: Both methods proved effective and safe for correction of myopia upto -6D.The results at our clinic are comparable with other departments and arestable in different years.PRKand LASIKachieve equal postoperative results afteran interval of 3 to 6 months following surgery.
