²Yeditepe Üniversitesi Göz Hastanesi, Göz Hastalıkları A.D., İstanbul, Prof. Dr. Purpose: Evaluation of micro-coaxial phacoemulsification and implantation of a blue light-filtering, aspheric, singlepiece, acrylic, hydrophobic intraocular lens.
Materials and Methods: In this prospective study, micro-coaxial phacoemulsification has been performed in 36 eyes with senile cataract, using the Intrepid System (Alcon®) through 2.4 mm clear corneal incision. A blue light-filtering, aspheric, single-piece, acrylic, hydrophobic intraocular lens (Acrysof IQ®, Alcon®) has been inserted via an injector without enlarging the incision. In the first postoperative month, routine ophthalmological examination is followed by contrast sensitivity tests (Vector Vision® CSV- 1000), wavefront examination and patient questionaire.
Results: Thirtysix eyes of 32 patients (14 male and 18 female), with a mean age of 71.28±10.09 years were included in the study. The preoperative uncorrected visual acuity (UCVA) improved from 0.25±0.22 to 0.91±0.17. There was no statistically significant difference between the postoperative photopic and mesopic contrast sensitivity measurements with and without glare (p=0.068 ve p=0.068). The postoperative mean higher order aberrations and mean aspheric aberrations were found to be low. Statistically significant results were detected from the questions related to daily activities and night vision (p<0.001).
Conclusion: Cataract operation with micro-coaxial technique induces less stress and trauma. Narrow tunnel incision together with the aspheric design of Acrysof® IQ improve the postoperative vision quality. The results of the questionaire support patient satisfaction.
