[Postoperative refraction and anterior chamber depth after complicated cataract operation with vitreous loss and transscleral posterior chamber lens fixation].

The accuracy of preoperative biometry was tested in patients with transscleral suture fixation of the posterior chamber lens. Postoperative refraction and anterior chamber depth of 34 eyes that had been subjected to complicated cataract extraction with vitreous loss were compared with those in 17 fellow-eyes in which uncomplicated cataract extraction had been performed. The anterior chamber depth was significantly deeper after transscleral suture fixation of the posterior chamber lens (mean 0.59 mm, P < 0.05). The refraction differed by +0.68 D between transscleral suture fixation and the control group. We recommend that +0.5 D should be added to the calculated intraocular lens power if transscleral suture fixation becomes necessary during cataract extraction.
