Clinical Evaluation of Traumatic Cataract with Corneal Laceration

The cataract extraction in traumatic cataract with corneal laceration is likely to be different from the ordinary cataract extraction in several points. We tried to know the problems of the operation, the visual outcomes and the postoperative complications in these eyes. In 25 traumatic cataract with corneal laceration, we performed cataract extraction and corneal suture at the same time in 11 eyes and at different time in 14 eyes. The intraoperative problems were difficult anterior capsulotomy, corneal opacity, difficult lens delivery etc.The major postoperative complications were anterior chamber inflammation, corneal edema, posterior capsular opacity and exudative pupillary membrane. In 23 eyes[92%], the visual acuity was increased more than 2 lines. Cataract extraction in traumatic cataract with corneal laceration was very effective surgery, and cataract extraction after primary corneal suture has done had good results in severe corneal laceration with suspicious posterior capsular rupture and non-fitted preoperative preparation.

Cataract Extraction in Vitrectomized Proliferative Diabetic Retinopathy

The cataract extraction in vitrectomized proliferative diabetic retinopathy(PDR) may be different from the ordinary non-vitrectomized patients in several points. We tried to know what`s the problems during the operation, how`s the visual outcomes and the postoperative complications in these eyes. In 18 previously vitrectomized PDR patients(25 eyes), we performed the extracapsular cataract extraction(ECCE) in 7 eyes and the phacoemulsification in 18 eyes. The intraoperative problems were insufficient dilation of pupil, unstability of (anterior and posterior) chamber depth, and difficulty in removal of cortex, which is firmly adherent to the posterior lens capsule. Opacity of posterior lens capsule, elevation of intraocular pressure, exudative pupillary membrane, posterior synechia and corneal edema were the major postoperative complications. In 22 eyes(88%), the visual acuity was increased more than 2 lines, Cataract extraction was easier and less postoperative complications these cases.
