Refractive and Visual Outcomes of a Monofocal Non-Constant Aberration Aspheric Intraocular Lens.

Purpose: To evaluate the refractive and visual outcomes following cataract surgery and implantation of a new monofocal non-constant aberration aspheric intraocular lens (IOL).

Methods: Ninety eyes of 86 patients who underwent implantation the CT LUCIA 621P IOL (Carl Zeiss Meditec AG) were retrospectively analyzed in this study. Main outcome measures were refractive error and monocular corrected distance visual acuity (CDVA) and monocular uncorrected distance visual acuity (UDVA) values.

Causes of intrastromal corneal ring segment explantation: clinicopathologic correlation analysis.

Purpose: To determine the main causes of intrastromal corneal ring segment (ICRS) explantation and the relationship with the microscopic findings on the ICRS surface.

Setting: Vissum Corporation-Instituto Oftalmológico de Alicante, Alicante, Spain.

Methods: This study evaluated ICRS that were explanted in centers in Spain from 2000 to 2008.
