Anterior keratotomy

Anterior keratotomy was analyzed in 200 myopic eyes. The cases were followed postoperatively every day for two weeks, thereafter at weekly intervals for about four months followed by monthly intervals for the rest of the period. There is 51% improvement in the visual acuity during the first week after the surgery. Thereafter up to the period of three months it is observed that 40% of the cases only retain 6/6 visual acuity, as a result of reduction of corneal flatness. This fall of vision in these cases is proportional to the degree of corneal flatness. There is no change in the field of vision. There is no change of accommodation and convergence, there is no change in the corneal thickness and the operation is useful in only 40% of cases.
