104 Ugur Onsal, Tugrul Akm, Omit Aykan, Ahmet Hamdi Bilge SUMMARY The Final Refractive Outcomes of Patients After Implantation of 3-Piece and Single Piece, 5.5 mm Acrylic lol Purpose: To compare the refractive status of patients, either implanted with 3-piece or single piece acrylic IOL during cataract surgery. Methods: In this prospective type study, 156 eyes of 149 patients implanted with 5.5 mm 3-piece acrylic IOL 153 eyes of 141 patients implanted with 5.5 mm single piece acrylic IOL were involved standart phacoemtilsification and 4.5-5.0 mm capsulorhexis were performed for both groups the patients were randomized into two groups. We evaluated the refractive status of the patients 1 and 6 months after postoperative period. The refractive results between +0.25 D and -0.25 D were accepted as emmetropy. The data found were analyzed by khi-square method statistically. Results: The postoperative refractive outcomes of 3-pieces acrylic IOL implanted patients are as follows; 135 eyes (86%) are between (+0.25 D, -0.25 D), 15 eyes (9.6%) are between(- 0,25 D,-1.00 D) and (+0,25 D, +1.00 D), 6 eyes (4.4%) are between (-1.00 D,-2.00 D) and ( + 1.00 D, +2.00 D). whereas the refractive status of patients implanted with single piece acrylic IOLs are 136 eyes (88.8%) are between (+0.25 D, -0.25 D), 14 eyes (9.1 %) are between (-0.25 D, -1.00 D) and (+0.25 D, +1.00 D), 3 eyes (2.1%) are between (-1.00 D, -2.00 D) and (+1.00 D, +2.00 D). Conclusion: The emmetropization after postoperative period upon IOL implantation is a difficult procedure. In this report there is no statistically important difference between those two groups implanted with the lens the same optical structure but different haptic structure it is also concluded that the initial period upon the implantation of single piece IOL's patients have been found slightly myopic and became more stabilized after the first month postoperatively. Key Words: Intraoculer lens (IOL) acrylic 3-piece IOL, acrylic single piece IOL, refractive outcome.

Hastalara uygulanan fakoemiil-sifikasyon ve katlanabilir GiL implantasyonu sonrasmda istenilen refraksiyona ve tashihsiz en yiiksek gorme keskinligine kavu mak kesif lensin aimmas! kadar onem ta ImaktadJr. Fakoemlilsifikasyon ve intraokliler lens implantasyonunun postoperatif donemdeki onemli sorunlanndan biri refraksiyon dlizeyidir. Preoperatif donemde yanh GiL hesaplamalanndan dolay1 postoperatif donemde olu an anizometropi nedeniyle GiL degi imi yap1lan olgular mevcuttur. Ameliyat sonras1 ideal refraksiyon ve tashihsiz garme keskinligine uht mak i9in gereken GiL glicii regresyon veya teoretik formiiller kullamlarak hcsaplanabilir (15, 16). Regresyon formlilleri i9inde en s1k kullamlan Saunders, Retlaff vc Kraff'm geli tirdigi SRK formlillidiir (17, 18). Bu formui uzun y!llar kullamld1ktan sonra aksiyel uzunlugun 22 ve 24.5 mm arasmda o1dugu gozlerde 9ok iyi sonur;: verdigi ancak bu sumlann di IIla 91- klldigmda yetersiz kaldigi saptanmi tir.

Her iki grupta da postoperatif refraktif sonu9lar birbirine yakm olup istatistiksel olarak anlamh fark yoktur. Bu r;:ah mada meydana gelen postoperatif refraksiyon diizeyleri literatiirle uyumluclur.
