AXIAL EYE LENGTH AND KERATOMETRIC CHANGES AFTER SCLERAL BUCKLING SURGERY
Abstract
Background. The objectivization of keratometric and axial length changes in patients with retinal detachment undergoing standard scleral buckling surgery procedure.
Patients and methods. Prospective evaluation of 40 patients with rhegmathogenus retinal detachment. We used STORZ Compuscan V2.00 to measure the axial length of the bulbus 1 week before surgery, 1 week and 3 months after surgery. We repeated the same time schedule for keratometric measurement; here we used ALCON keratometer.
Results and discussion. In most patients we found a lengthening of the globe and an increase of corneal astigmatism. Axial eye length was significantly increased 1 week after surgery (0,91 mm 1 week after surgery) but 3 months later there was no statistically significant difference (0.48 mm). Corneal astigmatism was also significantly increased 1 week after surgery (0.41 D), but 3 months later only minimal change remain (0.05 D).
Conclusions. In all cases of scleral buckling procedures axial length and keratometric changes are to be expected but at least 3 month after surgery they are not statistically significant any more.
