TitreMid-term results with the butterfly mini-incision intraocular lens
ButTo evaluate a new mini-incision single-piece acrylic intraocular lens (IOL).
MéthodesIn this single-surgeon prospective clinical trial, eyes from consecutive eligible patients planned for cataract surgery were included. Preoperative axial length measurements were performed with laser interferometry (IOL Master, Carl Zeiss). IOL power and target ametropia were calculated with SRKT and Haigis formulae. Torsional phacoemulsification was performed in a standardized fashion with implantation of the Butterfly (97B) IOL (Morcher, GmbH) through either 2.2 or 1.8 mm clear corneal incisions. Measures included uncorrected (UCVA), best spectacle corrected visual acuities (BSCVA), and postoperative deviation from target ametropia. Satisfaction rate, occurrence of dysphotopsia, YAG laser capsulotomy rate and IOL-related complications were also recorded.
Résultats263 eyes were included in the study, with a mean follow of 13.7 months. The mean deviations from target ametropia were 0.33 (SD 0.3) and 0.45 diopters (SD 0.37) after IOL power calculation with SRKT and Haigis formulae respectively. The mean deviation from subjective refraction recorded one month and twelve months after the operation was +0.11 diopters. YAG laser capsulotomies were performed in 8 eyes (3%), and dysphotopsia was reported by 6 patients (3.6%). To date, there was no report of IOL-related complication.
ConclusionMid-term results of this new mini-incision IOL suggest that this lens is safe, and achieve predictible and stable postoperative refraction. Posterior capsule opacification is low, but should be evaluated in the long term.
