Between January 1993 and June 1994, 98 sighted and partially sighted eyes of 62 patients had excimer laser photorefrac¬tive keratectomy (PRK) with the Chiron-Technolas Keracor 116 excimer laser using the single ablation zone protocol. The patients' mean preoperative spherical equivalent was -10,77 D ranging from -8,00D to -20.00D. The ages of 34 men and 28 women varied between 20 and 54 years (mean 33.2 years). 36 patients had bilateral PRK, 26 patients had unilateral PRK. Mean follow-up was 24 months. There were no serious complications or overcorrections in any of the patients. At 24 months, the patients' mean postoperative spherical equivalent was -2,55 D ranging from +0,50 D to -11,00 D. The data suggests that high myopia can be treated with reasonable success with this method however considering the high level of patient expectation from refractive surgery single zone excimer laser PRK is not clinically acceptable for high myopia and modifications of the technique is necessary.
