MICS+aspheric IOL = fewer corneal changes

Microincision cataract surgery (MICS) with implantation of an aspheric intraocular lens (IOL) through a 1.8 mm incision can minimize surgically-induced corneal and ocular aberrations and improve optical performance, according to a French study.

Microincision cataract surgery (MICS) with implantation of an aspheric intraocular lens (IOL) through a 1.8 mm incision can minimize surgically-induced corneal and ocular aberrations and improve optical performance, according to a French study.

Alexandre Denoyer and co-workers from Bretonneau University Hospital, France evaluated the postoperative corneal and ocular aberrations of 20 subjects following MICS with implantation of the aspheric MI60 IOL (Bausch & Lomb) through a 1.8 mm incision in one eye and through a 2.8 mm incision in the other eye.

The researchers found that changes in the corneal topography and aberrations were lower in the MICS group than in the other eye (p<0.05), as were the total ocular wavefront aberrations (p<0.05). Best corrected visual acuity and subjective visual comfort were similar in both groups.

Dr Denoyer concluded that MICS with implantation of an aspheric IOL can help minimize surgically-induced corneal changes.
