Anticoagulants and cataract surgery.
To evaluate complications resulting from increased bleeding, 2,178 cataract surgery patients, 28 of whom were on anticoagulants, were studied prospectively. The anticoagulated patients showed no increase in sight-threatening complications when compared to the nonanticoagulated cataract patients.
Posterior chamber pseudophakes in glaucoma patients.
In the past, glaucoma has been considered a relative contraindication to the use of an intraocular lens (IOL) in a patient undergoing cataract extraction. In this study, we examined postoperative intraocular pressure (IOP) control for three months postoperatively in 46 eyes with glaucoma undergoing cataract extraction with implantation of a posterior chamber IOL. Twenty-six eyes or 56.5% could be classified as having improved IOP control three months postoperatively. At the same time, 19 eyes or 41.3% demonstrated the same IOP control after lens implantation. Thus, 45 of the total of 46 eyes had as good or better postoperative IOP control. Of the 46 eyes, 100% required preoperative glaucoma medication, while postoperatively only 41% required medication.
