Abstract

Purpose : To evaluate results and complications in cataract surgery in patients with nanophthalmos patients in Mexican population.

Methods : Retrospective case series. We analyzed medical records of patients with diagnosis of nanophthalmos whom underwent cataract surgery from January 2007 to December 2014 from the Anterior Segment Department at Instituto de Oftalmologia Conde de Valenciana at Mexico City. The diagnosis of nanophthalmos was corroborated by axial length mode A echography (<21mm). Collected data included: surgery procedure, best-corrected visual acuity, intraocular tension, past ocular surgery history, and other ocular diagnosis –such as glaucoma; and associated complications.

Results : 343 electronic files of patients with diagnosis of nanophthalmos were reviewed. 19 patients underwent cataract surgery; we excluded 3 patients for misdiagnosis. All surgeries were performed by anterior segment specialists. Data of 15 eyes from 11 patients were analyzed. Mean age 61± 9.4 years-old (range 47-75). 73% female (8/15) and 27% male (4/15). 53% right eyes 46% left eyes. All patients underwent a phacoemulsification + intraocular lens implant, one required endocyclophotocoagulation during surgery. 86% of eyes reported some degree of lens opacity. 40% had previous diagnosis of angle-closure glaucoma, 2 patients history of iridotomies, 1 patient underwent trabeculotomy with mytomicin. 53% patients had initial best corrected visual acuity of >1 LogMAR. 20% had best corrected visual acuity of LogMAR >1 at 6 months follow up. 80% of eyes improved at least one line of visual acuity after surgery, 2 remain without changes, 1 decreased 2 lines of vision associated to corneal decompensation. No intra-operative complications were reported.

Conclusions : Anatomical features associated with nanophthalmos remain a challenge to the anterior segment surgeon due to the increased risk of intraoperative complications such as uveal effusion syndrome, serous retinal detachment, and cystic macular oedema. According to the experience at our Institution, surgical experience and improvement in surgical techniques allow higher success rates, security and improved visual outcomes, as reported above.
