³Afyon Kocatepe Üniversitesi Tıp Fakültesi Göz Hastalıkları A.D., Afyon, Prof. Dr. Purpose: To evaluate contrast sensitivity after hydrophilic acrylic single-piece intraocular lens (Zaraccom) implantation after uncomplicated phacoemulsification cataract surgery.
Materials and Methods: Twenty eyes of 20 patients after hydrophilic acrylic single-piece intraocular lens implantation (Zaraccom B155, Sivas, Turkey) were compared with 20 eyes of 20 patients after hydrophobic acrylic three-piece intraocular lens implantation (Sensar AR40e, AMO, Santa Ana, CA, USA) and 20 eyes of 20 age-matched normal subjects. All patients were operated on according to the standardized phacoemulsification procedure. The best corrected visual acuity and contrast sensitivity were measured at 3 months postoperatively. Contrast sensitivity at five spatial frequencies (1.5, 3, 6, 12, and 18 cycles per degree) was measured by Functional Acuity Contrast Test (Stereo Optical Co., Chicago, USA) under photopic conditions (85 cd/m²).
Results: Postoperative BCVA was -0.002±0.01 logMAR in the Zaraccom group. There were no statistically significant differences in BCVA between the groups (p>0.05). In the Zaraccom group, contrast sensitivity scores at 6, 12, and 18 cycles per degree were lower than those in the Sensar AR40e group at 3 months but there was no statistically significant difference in spatial frequencies between the groups (p>0.05).
Conclusion: Zaraccom intraocular lens implantation provided contrast sensitivity comparable to that obtained with the Sensar AR40e 3 months after implantation. Keywords : Zaraccom, contrast sensitivity, intraocular lens, phacoemulsification
