We treated 60 eyes with corneal diseases using a repetitive short-pulsed excimer laser using argon fluoride with the wavelength of 193 nm. The series comprised pterygium 29 eyes, corneal leucoma 12 eyes, band keratopathy 8 cases, granular dystrophy 5 eyes, corneal ulcer 3 eyes and corneal herpes 3 eyes. The treatment was conducted under an oper-ating microscope with the patient in recumbentposition.

The treatment was effective in removing corneal opacity. The treated area was sharply defined in area and depth. Visual acuity improved immediate-ly after treatment. No clinically observable edema developed in the neighboring cornea. Ablated sur-face showed smooth and apparently normal reepi-thelialization.

During the follow up period ranging 4 to 12 months, postoperative hyperoptic shift and slight haze beneath the ablated area appeared to be a problem. These complications were temporary and disappeared 3 months after treatment. The findings suggest that excimer laser can be a safe and effec-tive therapeutic means in superficial corneal dis-eases.
