To evaluate the timing and outcomes of cataract surgery in patients with keratoconus.
Retrospective interventional case series. Records of patients diagnosed with keratoconus who underwent cataract surgery were reviewed. Eyes were stratified by timing of cataract surgery in relation to corneal transplantation. Preoperative and postoperative best corrected visual acuity (BCVA) at 1 month and 1 year, and manifest refractive spherical equivalent (MRSE) were compared.
2011-2013. 31 eyes with keratoconus undergoing cataract surgery were identified. 14 eyes underwent cataract surgery only. 10 underwent cataract surgery following corneal transplantation. 6 eyes underwent combined cataract surgery and corneal transplantation. 1 eye underwent corneal transplantation following cataract surgery. Preoperative BCVA was best in the eye undergoing corneal transplantation following cataract surgery and worst in eyes undergoing combined surgery. Postoperative BCVA and MRSE was best in eyes undergoing cataract surgery following corneal transplantation and worst in eyes undergoing combined surgery. The worst visual outcomes were non-refractive in nature.
The timing of cataract surgery in relation to corneal transplantation may affect the results achieved.
