Abstract:
PURPOSE: To evaluate the influence of pupil size on uncorrected visual acuity and spherical aberration of the TECNIS 1-piece intraocular lens (IOL). METHODS: In this study 61 eyes were implanted with a TECNIS 1-piece IOL. Pupil size was checked by standard pupil card with cobalt blue light postoperatively. Best corrected visual acuity (BCVA) and uncorrected visual acuity (UCVA) were assessed postoperatively. Total spherical aberration and high-order aberration for mesopic pupil size zone were measured. RESULTS: There were no significant differences of spherical equivalent, age, preoperative astigmatism, BCVA between two groups, but small pupil group revealed better UCVA (p = 0.02) and lower ocular aberration than large pupil group. CONCLUSIONS: After cataract surgery, pupil size greater than 5.0 mm increases total aberration. Thus, visual acuity with small pupil after aspheric TECNIS 1-piece IOL implantation show better clinical result on uncorrected visual acuity.
