Analysis of changes in corneal shape and bulbus geometry after retinal detachment surgery.

Purpose: To investigate changes in corneal shape and anterior segment following retinal detachment surgery.

Material And Methods: 25 consecutive patients with retinal detachment were enrolled in this study. Computer-assisted videokeratography was performed before and after retinal detachment surgery and changes in the anterior segments of postoperative patients were also noted.

Results: In the local buckling group, statistically significant changes were observed in the anterior chamber depth, lens thickness, and vitreous length (distance from posterior surface of lens to the retina) in the postoperative period. However, in the encircling group, statistically meaningful changes were observed in the vitreous length, axial length of the globe, and the central corneal curvature and thickness in the postoperative period.

Conclusion: Corneal topography and axial measurements may be useful for evaluating the shape of the cornea after retinal detachment surgery. Because the resultant refractive changes are very important for the visual rehabilitation of the patients.
