There is limited data on refractive outcomes of multifocal intraocular lens (IOL) implantation with creation of limbal relaxing incisions. We assessed the effect on visual outcomes of limbal relaxing incisions at the time of multifocal intraocular lens implantation in a retrospective, observational study.
Charts were reviewed for patients who underwent limbal relaxing incisions at the time of cataract extraction by phacoemulsification with implantation of a multifocal IOL by a single surgeon in one hospital between January 1, 2012 and March 1, 2016. The Donnenfield nomogram and the AMO LRI calculator software were used to plan LRI placement and size. Record of preoperative visits, at least one postoperative visit, operative reports, preoperative IOLMaster biometry, and LRI calculator results were necessary for the study. This study includes 27 eyes from 24 patients. 13 patients were female (54%) and 11 were male (46%). The average age was 67.5 years. There were 14 right eyes and 13 left eyes. Microsoft Excel was used to analyze results.
There was an average 0.94D of preoperative corneal astigmatism. Twenty-two (81%) of eyes achieved a distance visual acuity of 20/40 or better by the last recorded follow-up.
There was a trend toward improved visual outcomes with limbal relaxing incisions at the time of phacoemulsification and multifocal lens implantation. This was a limited retrospective study, and an expanded prospective study would investigate outcomes more thoroughly and definitively.
