³Beyoğlu Göz Eğitim ve Araştırma Hastanesi, Göz Hastalıkları, İstanbul, Prof. Dr. Purpose: To evaluate the changes of refractive values in pseudophakic eyes with posterior capsular opacification after Nd:YAG laser capsulotomy.
Materials and Methods: In this prospective study, fifty-six eyes of fifty-one patients (28 male, 23 female) having Nd:YAG laser capsulotomy for posterior capsular opacification were recruited. The mean age was 63.6±14.6(SD). The refractive status, uncorrected visual acuity and best corrected visual acuity of the patients were measured before laser and first week after.
Results: The mean pre-treatment spherical and cylindrical values with autorefractometer were -0.43±3.42 D and -2.01±1.27 D respectively and post-treatment values were -0.45±3.18 D and -1.14±0.81 D respectively. While the reduction of mean cylindrical value was significant, (p<0.001) there was no statistically significant change in the mean spherical value (p=0.87). The mean uncorrected and best corrected visual acuities were improved significantly after posterior capsulotomy.
Conclusion: Nd:YAG laser capsulotomy is an effective and safe alternative for the treatment of posterior capsular opacification. Although Nd:YAG laser posterior capsulotomy did not significantly change the spherical values, it decreased the astigmatic values at 1st week examination following treatment.
