Predictive factors for photic phenomena after refractive, rotationally asymmetric, multifocal intraocular lens implantation.

چکیده
AIM To investigate the independent factors associated with photic phenomena in patients implanted with refractive, rotationally asymmetric, multifocal intraocular lenses (MIOLs). METHODS Thirty-four eyes of 34 patients who underwent unilateral cataract surgery, followed by implantation of rotationally asymmetric MIOLs were included. Distance and near visual acuity outcomes, intraocular aberrations, preferred reading distances, preoperative and postoperative refractive errors, mesopic and photopic pupil diameters, and the mesopic and photopic kappa angles were assessed. Patients were also administered a satisfaction survey. Photic phenomena were graded by questionnaire. Independent-related factors were identified by correlation and bivariate logistic regression analyses. RESULTS The distance from the photopic to the mesopic pupil center (pupil center shift) was significantly associated with glare/halo symptoms [odds ratio (OR)=2.065, 95% confidence interval (CI)=0.916-4.679, P=0.006] and night vision problems (OR=1.832, 95% CI=0.721-2.158, P=0.007). The preoperative photopic angle kappa was significantly associated with glare/halo symptoms (OR=2.155, 95% CI=1.065-4.362, P=0.041). The photopic angle kappa was also significantly associated with glare/halo symptoms (OR=2.155, 95% CI=1.065-4.362, P=0.041) and with night vision problems (OR=1.832, 95% CI=0.721-2.158, P=0.007) in patients implanted with rotationally asymmetric MIOLs. CONCLUSION A large pupil center shift and misalignment between the visual and pupillary axis (angle kappa) may play a role in the occurrence of photic phenomena after implantation of rotationally asymmetric MIOLs.

To the Editor: I commend Munoz et al on their well-designed and well-conducted study on the clinical effect of a combination of multifocal intraocular lenses (MIOL) including the newest rotationally asymmetric MIOL, which appeared in the March 2012 issue of the Journal of Refractive Surgery.1 They found that contrast sensitivity was comparable to that achievable with a monofocal implant and, re...

The main goal of a presbyopic patient is to reduce dependence on optical aids and improve both distance and near vision as well as the range of clear vision. Several studies report good safety, predictability, and efficacy outcomes in the implantation with monofocal, toric and multifocal intraocular lenses (IOLs) after refractive lens exchange (RLE). Patients with hybrid spherical IOLs show goo...
