Abstract
Amaç: Kataraktı ve astigmatizması olan hastalarda astigmatizmayı düzeltmek için Tecnis toric İOL ile Acrysof toric İOL’lerinin görsel sonuçlarının kıyaslanması.
Gereç ve Yöntemler: Otuz sekiz hastanın 38 gözüne Tecnis torik İOL, 36 hastanın 36 gözüne Acrysoft torik İOL implante edeildi. Hastaların kataraktı ve astigmatizması vardı. Ameliyatlarda 7 çeşit Tecnis torik İOL (: ZCT150, ZCT225, ZCT300, ZCT400, ZCT450, ZCT525, and ZCT600),7 ceşit, Acrysof torik İOL (SN6AT3, SN6AT4, SN6AT5, SN6AT6, SN6AT7, SN6AT8, and SN6AT9) kullanıldı . İOL’lerin astigmatik değerleri 1.50 ile 6.00 D arasındaydı.Hastaların düzeltilmemiş görme keskinliği (DGK) ve en iyi düzeltilmiş görme keskinliği (EDGK), keratometre, refraktif ölçümleri ve İOL’ün aks hizası düzenli aralıklarla kontrol edilmiştir.
Bulgular: Her iki grupta ortalama postoperatif sferik ve silendirik değerler preoperatif değerlerden anlamlı şekilde daha düşüktü (P<0.05) ve ortalama postoperatif DGK ve EDGK değerleri preoperatif değerlerden anlamlı olarak daha yüksekti (p<0.05). DGK, EDGK, sferik ve silendirik değerler açısından iki grup arasında istatistiksel olarak anlamlı bir fark saptanmadı (p>0.05).
Sonuç: Hem Tecnis torik İOL hemde Acrysof torik İOL implantasyonunun , katarakt cerrahisi sırasında var olan korneal astigmatizmayı düzeltmek için etkin olduğu izlenmiştir. İkinci grup (Acrysof toric) hastaların ameliyat sonrası ortalama görme keskinlikleri, birinci grup (Tecnis toric) hastalara göre biraz daha iyi olmasına rağmen istatistiksel olarak anlamlı bir farklılık yoktu.

Abstract
Purpose To compare the visual outcomes of Tecnis toric IOL and Acrysof toric IOL implantations in patients with cataract and astigmatism retrospectively.
Methods: Tecnis toric IOLs were implanted in 38 eyes of 38 patients, and Acrysof toric IOLs were implanted in 36 eyes of 36 patients. The patients had cataract and astigmatism. During the surgeries we used 7 kinds of Tecnis toric IOL: ZCT150, ZCT225, ZCT300, ZCT400, ZCT450, ZCT525, and ZCT600, cylindrical power was between 1.50 D and 6.00 D and 7 kinds of Acrysof toric IOL: SN6AT3, SN6AT4, SN6AT5, SN6AT6, SN6AT7, SN6AT8, and SN6AT9, cylindrical power was between 1.50 D and 6.00 D. Uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA), keratometric and refractive measurements, and IOL axis were tested in follow-up examinations.
Results: Postoperative mean spherical and cylindrical values of both groups were significantly lower than those of preoperative values (p<0.05),and postoperative mean UCVA and BCVA levels of both groups were significantly higher than preoperative levels (p<0.05). When we compared the two groups (Tecnis toric and Acrysof toric), there were no significant differences in respect to UCVA, BCVA, spherical and cylindrical values (p>0.05).
Conclusion: Both Tecnis toric and Acrysof toric IOL implantations during cataract extraction operation are effective in reducing astigmatism. Even though postoperative visual acuities of the second group (Acrysof toric) were slightly better than those of the first group (Tecnis toric), the difference was not statistically significant.
