[Depth visual function and the relative accommodation reserves of patients before and after keratotomy]

Reserves of relative accommodation and thresholds of remote vision have been investigated in 60 patients with myopia of different degree before radial keratotomy and 1.5-2.0 years after the surgery. It was firstly established that the state of accommodation and remote vision for near before surgery influences the stability of the obtained postoperative effect. This fact should be considered when planning keratotomy. A conclusion is made that for patients with reserves of accommodation of the positive part not lower that 2.0D and the threshold of remote vision for near not higher than 7 mm keratotomy is not advisable.
