Secondary laser in situ keratomileusis 1 year after primary LASIK for high myopia.

PURPOSE: To report the results of the laser in situ keratomileusis (LASIK) using a second-cut hinged corneal flap to treat regression 1 year after primary LASIK for high myopia. SETTING: Istanbul University, Eye Research Center, Istanbul, Turkey. METHODS: Six eyes of 4 patients who had a mean myopic regression of -6.20 diopters (D) +/- 1.10 (SD) 1 year after primary LASIK were retreated with secondary LASIK performed using the Automated Corneal Shaper (Chiron Vision) and a 193 nm excimer laser (Chiron Technolas, Keracor 116). Fluence was 130 mJ/cm2 and the repetition rate, 10 Hz. RESULTS: Mean follow-up was 12.16 +/- 0.75 months. At the last follow-up, the mean spherical equivalent was -0.18 +/- 0.77 D (range +0.12 to -1.25 D). Two eyes (33.3%) remained within +/- 0.50 D of emmetropia; 5 eyes (83.3%) were within +/- 1.00 D of emmetropia. No patient lost best spectacle-corrected visual acuity. No complications occurred such as detachment of the former corneal flap and rolling, irregularity, or tearing of the new corneal flap. CONCLUSION: Secondary LASIK was an effective, safe method to treat regression after primary LASIK for high myopia.

Short term cyclosporin A treatment of Behçet's disease.

Eleven separate three-month courses of cyclosporin A, an oral solution 10 mg/kg/day, were administered to eight patients with Behçet's disease with sight-threatening posterior uveitis. It was found to be effective in arresting the inflammatory activity in the eye as well as the mucocutaneous lesions of Behçet's disease. Improvement in visual acuity was observed within one week of starting therapy. Severe exacerbations in the ocular and mucocutaneous lesions occurred on withdrawal of the drug. At this dosage side effects included hirsutism in all women, and a slight rise of serum bilirubins in two patients and of blood urea in one patient. The latter two conditions responded rapidly to dose adjustment.

Simultaneous and sequential photorefractive keratectomy.

The purpose of this study was to show the safety, effectiveness, and predictability of simultaneous bilateral as compared to sequential unilateral photorefractive keratectomy in 273 normally sighted myopic eyes. An excimer laser with a fluence of 180 mj/cm2 at a frequency of 10 Hz was used at three ablation zones (5 mm, 6 mm, and 6.5 mm). There were no significant differences between the two groups' results. Mean refraction at six months was 0.34-0.96 D in group 1 simultaneous group and 0.32-0.95 D in group 2 sequential group. At 9 months after surgery, 84% of eyes had an uncorrected visual acuity of at least 20/40. The average pain score on the first postoperative day was 2.4 for group 1 simultaneous group and 2.3 for group 2 sequential group. No serious complications occurred. Despite the short follow up, simultaneous bilateral photorefractive keratectomy appears to be an effective and safe procedure for the correction of myopia.
