![]() ![]() This may not be obvious to preoperative examination but can lead to a very unpleasant surprise of an open capsule during surgery. Occasionally in these patients, especially those who had vitrectomy performed, the posterior capsule may have been damaged inadvertently by the retina surgeon. (In general, we do not recommend presbyopia-correcting implants when a potential acuity is any less than 20/25.)Īnother pitfall of post-retinal detachment cataract surgery is uncertainty about the lens capsule. For this reason, we would not recommend a multifocal implant, as we assumed his vision could only improve to about the 20/40 to 20/50 range. In the case of the patient mentioned above, OCT testing revealed fairly significant macular distortion, which explained why vision never seemed to recover to normal, even in the period after cataract but before evaluation in our office. In some types of cataract, the use of a potential acuity meter test can isolate macular acuity, but only if the cataract is not too dense and has a clear region optically to project the eye chart around the opaque areas of the cataract. Ocular coherence tomography can assist in identifying anatomic defects, but is not always capable of assessing the capacity for normal vision. Naturally this can be difficult to assess by exam through an opaque cataract. Several possible pitfalls can limit visual potential after cataract surgery in the patient who has had retinal detachment repair.įirst, epiretinal membranes may form and, even in the absence of such a membrane, distortion of the macula frequently occurs and will reduce both Snellen acuity and quality of vision. ![]() Additionally, the surgical trauma of retinal detachment repair can itself cause enough trauma to the lens to induce cataract. These gases frequently disrupt the metabolism of the crystalline lens, rendering it opaque within just a few months after surgery. The patient, a classic type-A personality, was very interested in a multifocal lens for spectacle independence and repeatedly asked about this possibility.Ĭataract surgery is frequently necessary following retinal detachment repair, especially when intravitreal gas is applied to close a retinal break and reattach the retina. He never recalled recovering completely normal vision after his detachment repair. If you continue to have this issue please contact to HealioĪ 57-year-old patient with a history of retinal detachment in his right eye developed significant posterior subcapsular cataract 3 months after successful repair of his detachment. ![]()
