Recently, intraocular lenses (IOLs) started to have additional function such as aspheric and yellow tinted; however, the clinical effects of these functions are still unclear. In this study, we evaluated clinical results and visual quality after different functionalized (spherical, aspheric and yellow tinted) IOLs implantation.
In randomized retrospective study, 41 patients were implanted 3 different types of IOLs: Spherical IOL (SP; Alcon SA60AT, 15 eyes), Aspheric IOL (AP; AMO ZA9003, 26 eyes) and Yellow tinted IOL (YT; HOYA YA60-BB, 24 eyes). Ophthalmologic examination including best-spectacle corrected visual acuity (BCVA), intraocular pressure (IOP), flare in anterior chamber, corneal endothelial cells density (CECD), glare disability, and contrast sensitivity were measured preoperatively, 1 week, 1 month, and 3 months postoperatively. For evaluation of visual performance, contrast sensitivity was measured in different light conditions (half dark condition, 18-20 lux; dark condition 1-2 lux).
There are no difference about BCVA, IOP, flare and CECD using 3 IOLs. The glare disability of AP IOLs (5.0±3.5 %) was smaller than the glare disability of SP IOLs (10.0±5.9 %) and YT IOLs (7.7±4.6 %). Furthermore, the results of contrast sensitivities showed that AP IOLs were greater than SP IOLs and YT IOLs significantly in half dark condition. The advantage of contrast sensitivities using AP IOL is greater in dark condition than in the half dark condition.
The clinical results of functionalized IOLs were preferable. The aspheric IOL demonstrated greater visual performance in dark conditions because of the wider pupil increased the aspheric effect.
