Abstract

Aim: To investigate the progression of binocular vision of patients after cataract surgery in the early postoperative period. Materials and methods: Eighty four cataract patients were evaluated at postoperative 1 and 3 months after phacoemulsification and posterior chamber monofocal lens implantation. For the evaluation of the grades of binocular vision, synoptophore was used. Stereoscopic acuity was measured with the Titmus Stereotest. Results: Evaluation at postoperative 3 months was associated with a significantly higher proportion of patients with stereopsis (P = 0.004), better levels of stereoacuities (P < 0.001) than the evaluation at postoperative 1 month. Significantly higher visual acuities (P = 0.001) and lower interocular difference in refraction values (P = 0.023) were also noted at postoperative 3 months. The level of stereoscopic acuity was not significantly correlated with the level of visual acuity, interocular visual acuity difference, interocular difference in refraction, and the age of patients (P > 0.05). In patients without fusion, suppression was found in the operated eyes with favorable visual acuities, and even in some of those with higher visual acuities compared to the fellow eye. Conclusion: During the early postoperative period of cataract patients, improvements in binocular vision were observed, which may be attributed to neural factors along with optical factors because of the cerebral basis for binocular vision.
