Patients with high myopia had the greatest improvement in stereopsis after PRK compared with low myopic and hyperopic patients (P < .001). The improvement in stereoacuity was significantly higher in the severe anisometropic group; the lowest improvement was in the group without anisometropia.Photorefractive keratectomy could result in an improvement in stereopsis. Patients with high myopia benefitted most from PRK in terms of improvement in stereopsis.None of the authors has

111. Comparison of the effect of cycloplegic versus NSAID eye drops on pain after photorefractive keratectomy. Full Text available with Trip Pro

Comparison of the effect of cycloplegic versus NSAID eye drops on pain after photorefractive keratectomy. To compare the effect of Homatropine and Diclofenac eye drops for reducing pain after photorefractive keratectomy (PRK).This randomized, double-masked, interventional study included 32 patients (64 eyes) who underwent bilateral PRK. After operation, patients received Homatropine eye drops in one eye and Diclofenac eye drops in the fellow eye for 48 h. The level of pain was evaluated using (...) in the Diclofenac eyes (1.6 ± 1.8 vs 3.4 ± 2.8, P < 0.001 for VAS, 0.6 ± 0.6 vs 1.2 ± 0.9, P < 0.001 for VRS, and 3.3 ± 3.7 vs 6.5 ± 6.2, P < 0.001 for PRI). No case with delayed epithelial healing in both groups was observed.The effect of Homatropine seems to be lower compared to Diclofenac for reducing pain after photorefractive keratectomy.
