[Long-term clinical course of laser in situ keratomileusis--two year follow-up].

PURPOSE: To evaluate the cases that were treated with laser in situ keratomileusis (LASIK) and who were follwed up for a full 2-year period without fail. MATERIALS AND METHODS: LASIK was performed in 62 eyes of 35 patients between June 1997 and March 1999. Mean age was 29.1 years and the preoperative mean spherical equivalent refraction was -6.90 +/- 2.49 (mean +/- standard deviation) diopter (D). Five aspects were studied as follows. RESULTS: 1. SAFETY: 26 eyes (41.9%) gained 1 line or more in best corrected visual acuity. Twenty eyes (32.3%) were unchanged. Sixteen eyes(25.8%) lost 1 line. No eye lost 2 lines or more. The safety index was 1.04. 2. EFFICACY: The efficacy index was 0.85. 3. Predictability: Forty-eight eyes (77.4%) were predictable within +/- 0.5 D, and 55 eyes (88.7%) were within +/- 1.0 D. 4. Stability: Manifest refraction was relatively stable after 3 months. 5. Complication: No complications were experienced. CONCLUSIONS: Our 2-year follow-up showed that postoperatively LASIK was safe and effective.

Clinical outcomes of wavefront-guided laser in situ keratomileusis: 6-month follow-up.

PURPOSE: To evaluate the clinical outcomes 6 months after wavefront-guided laser in situ keratomileusis (LASIK) for myopia in Japan. SETTING: Department of Ophthalmology, Sanno Hospital, Tokyo, Japan. METHODS: This prospective study comprised 22 eyes of 12 patients treated with wavefront-guided LASIK who were available for evaluation at 6 months. The mean patient age was 31.2 years +/- 8.4 (SD) (range 23 to 50 years), and the mean preoperative spherical equivalent refraction was -7.30 +/- 2.72 diopters (D) (range -2.75 to -11.88 D). In all cases, preoperative wavefront analysis was performed with a Hartmann-Shack aberrometer and the Technolas 217z flying-spot excimer laser system (Bausch & Lomb) was used with 1.0 mm and 2.0 mm spot sizes and an active eye tracker with a 120 Hz tracking rate. The clinical outcomes of wavefront-guided LASIK were evaluated in terms of safety, efficacy, predictability, stability, complications, and preoperative and postoperative aberrations. RESULTS: At 6 months, 10 eyes had no change in best spectacle-correct visual acuity and 10 gained 1 or more lines. The safety index was 1.11 and the efficacy index, 0.82. Slight undercorrections were observed in highly myopic eyes. In all eyes, the postoperative refraction tended slightly toward myopia for 3 months and stabilized after that. No complication such as epithelial ingrowth, diffuse lamellar keratitis, or infection was observed. Comparison of the preoperative and postoperative aberrations showed that 2nd-order aberrations decreased and higher-order aberrations increased. In the 3rd order, aberrations increased in the high-myopia group (-6.0 D or worse) and decreased in the low to moderate-myopia group (better than -6.0 D). CONCLUSION: Wavefront-guided LASIK was a good option for refractive surgery, although a longer follow-up in a larger study is required.

[Late onset diffuse lamellar keratitis].

BACKGROUND: Diffuse lamellar keratitis (DLK) is marked by the presence of diffuse or multifocal infiltrates confined to the laser in situ keratomileusis(LASIK) interface. These infiltrates are culture-negative, and the etiology is thought to be noninfectious. Most cases of DLK occur within the first week or two following surgery. CASE: We describe two cases of diffuse lamellar keratitis that occurred 3 months after LASIK. These patients were treated with intensive topical corticosteroids. RESULTS: We treated the patients with topical corticosteroids, with rapid improvement in patient symptoms, visual acuity, and slit-lamp biomicroscopy. CONCLUSION: DLK may occur three months after LASIK.

CASES: We described 2 cases of DLK that occurred 3 months after LASIK. These patients were treated with intensive topical corticosteroids. RESULTS: Treatment with topical corticosteroid was instituted, with rapid improvement in patient symptoms, visual acuity, and slit-lamp biomicroscopic findings. CONCLUSION: DLK may occur as late as 3 months after LASIK.
