Abstract

PURPOSE
To evaluate the effect of scleral buckling and pars plana vitrectomy on accommodative power. METHODS: The study groups consisted of 30 eyes after buckling and 30 eyes after pars plana vitrectomy. Each control group comprised 30 eyes. Accommodative power, pupil diameter and anterior chamber depth were measured and the correlation coefficient to accommodative power was calculated. RESULTS: There was no statistical significance in the buckling group. In the pars plana vitrectomy and control groups, the accommodative powers were 4.03 +/- 2.30D and 2.26 +/- 2.70D (p<0.05), and the pupil diameters were 3.07 +/- 1.06 mm and 3.99 +/- 2.71 mm (p<0.05), respectively. Age and pupil diameter had a significant correlation coefficient in all groups (r>0.8 or r<-0.8). CONCLUSIONS: After pars plana vitrectomy, the accommodative power was increased, which suggested that the anatomical and structural change of the vitreous after pars plana vitrectomy influences the accommodative power.
