Excimer laser treatment of hyperopia [PDF]
Acta Ophthalmologica Scandinavica, 1998 The aim of this study was to analyse the clinical results of hyperopic photorefractive keratectomy treatments and to compare the results achieved with the usage of different masks.20 eyes of 16 hyperopic patients were treated, using the Aesculap-Meditec MEL60 193nm ArF excimer laser. The mean duration of follow-up was 9.9+/-3.4 months.

The effect of unilateral disruption of the centrifugal visual system on normal eye development in chicks raised under constant light conditions [PDF]
, 2016 The centrifugal visual system (CVS) comprises a visually driven isthmic feedback projection to the retina. While its function has remained elusive, we have previously shown that, under otherwise normal conditions, unilateral disconnection of centrifugal ...
