Abstract Details

Purpose:

The purpose of this study was to analyse corneal higher-order aberrations (HOA) after phacoemulsification in three groups of patients with different incision sizes.

Setting:

A total of 109 eyes of 89 patients were enrolled in this retrospective, single-center study (mean age: 73.7 years +/- 8.9). The cataract patients underwent phacoemulsification with implantation of an intraocular lens (IOL).

Methods:

The following incisions were made: 1.4 mm with biaxial microincision phacoemulsification (B-MICS, 20 eyes) followed by an implantation of a microincision aspheric intraocular lens Incise MJ14T (Bausch & Lomb), 1.8 mm with coaxial phacoemulsification and implantation of an Akreos MI60 (C-MICS, Bausch & Lomb, 27 eyes) and 2.2 mm coaxial phacoemulsificaton with implantation of an aspheric IOL (SICS, Tecnis ZCB00, Abbott Medical Optics / CT Asphina, Carl Zeiss Meditec / Hoya iSert 251, HOYA, 62 eyes). Aberrometry was performed using an iTrace aberrometer with a pupil scan size of 5.0 mm preoperatively and at postoperative follow-up visits after 1 month.

Results:

In all groups an increase of total higher-order aberrations could be measured. However, a statistically significant difference was only seen in the 2.2 mm group (p=0.014). With regard to Coma, Spherical Aberration and Trefoil, in none of the groups a statistical significance could be shown.

Conclusions:

The 2.2 mm incision seems to have the most impact on total corneal higher-order aberrations in comparison to 1.4 mm and 1.8 mm incisions.
