Laser in Situ Keratomileusis Outcomes among Myopic and Myopic Astigmatism Patients with Thin Cornea
To evaluate refractive results after laser in situ keratomileusis among patients with thin corneas.Patients and
Three hundred and two eyes from 168 patients with thin corneas undergoing laser in situ keratomileusis in Basir Eye Clinic, Tehran, Iran, were retrospectively studied. We included patients with best corrected visual acuity of better than 6/12, age of more than 18 years, and corneal thickness of less than 499 μm.
The mean age of patients was 30.7 ± 8.6 years and the mean preoperative spherical equivalent was - 4.61 ± 2.37 D. The results after at least one year of follow-up were as follow: 86.6 % of patients with low myopia, 71.8 % of patients with mild myopia, 50.0 % of patients with moderate myopia and 51.8 % of patients with high myopia achieved a ± 0.5 D spherical equivalent postoperatively. General linear model indicated a significant effect for the remaining stromal bed on final uncorrected visual acuity after adjustment for age, sex, and degree of myopia. No important complication occurred.
No important complications occurred after laser in situ keratomileusis among myopic patients with corneal thickness of less than 499 μm, and most of the patients achieved satisfactory refractive results.Keywords: Laser in Situ Keratomileusis; outcome; myopia; thin cornea; Iran.
