PURPOSE: To evaluate the effectiveness, predictability, and safety of laser in situ keratomileusis (LASIK) for correcting myopia greater than -10.00 D. METHODS: Sixty-five eyes of 37 patients with myopia greater than -10.00 D underwent LASIK. Patients were evaluated on day 1, 1 week, 1, 3, and 6 months after surgery. Parameters evaluated were uncorrected visual acuity (UCVA) and best spectacle- corrected visual acuity (BSCVA), residual refractive error, regression of correction, and presence of any complication. RESULTS: Mean preoperative BSCVA was 0.745 ± 0.234, which improved to 0.8070 ± 0.237 postoperatively. The average preoperative UCVA was 0.022 ± 0.02; postoperative UCVA at 6 months was 0.536 ± 0.255. UCVA of 20/40 or better was achieved in 58% (38 eyes) and 20/20 or better in 26% (17 eyes). The average refractive error before LASIK was -12.64 ± 2.16 D (range -10.00 to -19.00 D). Mean residual refractive error 1 week following LASIK was -0.63 ± 1.36 D, which regressed to a mean -1.78 ± 2.08 D at the end of 6 months. Nineteen eyes (29%) were within ±0.50 D of intended refractive correction. CONCLUSION: LASIK was partially effective in the correction of high myopia. An initial overcorrection may be programmed to offset the effect of refractive regression. [ABSTRACT FROM AUTHOR]

Abstract Aim: To study the demographic pattern and indications for evisceration in north India and to evaluate the changing trends over the last decade. Methods: In a retrospective hospital-based study, case records of all patients who underwent evisceration at Rajendra Prasad Centre for Ophthalmic Sciences from January 1990 to December 1999 were reviewed. The parameters evaluated were the age and sex distribution, the place of residence (urban/rural) and the indications for evisceration. The aetiology responsible for evisceration was determined on the basis of history, clinical examination and investigations as determined from previous records. Results: One hundred and sixty-four patients had one eye eviscerated during the study period. The mean age of the patients was 51 ± 13.84 years (range 6 months to 90 years). Panophthalmitis was the most common indication for evisceration (78.6%, n = 129), followed by irreparable globe injury (21.3%, n = 35). There was a significant decrease in the eviscerations performed due to pano-phthalmitis from 104 cases during the period 1990-1994, to 25 cases in the period 1995-1999. Conclusion: Panophthalmitis and severe ocular injury are the major indications of evisceration in north India. There has been a significant decrease in the number of eviscerations related to panophthalmitis over the last decade. [ABSTRACT FROM AUTHOR]
