CONCLUSION: It has been concluded that the tunnel incisions uridened up to 6.5 mm during the operation did not cause significant astigmatic changes in the cornea.

Objective & Hypothesis:PURPOSE: We evaluated the topographic analysis of corneas in patients who underwent phacoemulsification and intraocular lens (IOL) implantation.
📊
Key Findings & Data:MATERIAL AND METHOD: The group consisted of 271 eyes of 224 eases who underwent foldable, 5.0 mm or 6.5 mm IOL implantation following phacoemulsification, The mean age of this group was 63.1 ±11.8 (14-90). in this group the surface regularity index (SRI), surface asymmetry index (SAI), simulated keratometry (SimK1, SimK2) and minumum keratometric value (Min K) were evaluated using quantitative corneal topographic indices, the findings at the preoperative period were compared with the values at the postoperative day, 1 st week and 1 st month.

Abstract

PURPOSE: We evaluated the topographic analysis of corneas in patients who underwent phacoemulsification and intraocular lens (IOL) implantation. MATERIAL AND METHOD: The group consisted of 271 eyes of 224 eases who underwent foldable, 5.0 mm or 6.5 mm IOL implantation following phacoemulsification, The mean age of this group was 63.1 ±11.8 (14-90). in this group the surface regularity index (SRI), surface asymmetry index (SAI), simulated keratometry (SimK1, SimK2) and minumum keratometric value (Min K) were evaluated using quantitative corneal topographic indices, the findings at the preoperative period were compared with the values at the postoperative day, 1 st week and 1 st month. RESULTS: As the result, we did not observe statistical difference except the SRI values of 6.5 mm IOL implanted cases at the postoperative 1st day. The SRI and SAI values were found to be higher at the postoperative 1st day in comparison to the preoperative values whereas it decreased to the preoperative values at the postoperative 1st month. CONCLUSION: It has been concluded that the tunnel incisions uridened up to 6.5 mm during the operation did not cause significant astigmatic changes in the cornea.

Özet

AMAÇ: Fakoemülsifikasyon ile göz içi mercek (GİM) implantasyonu uygulanan hasta kornealarında, korneal topografik analiz için çalışma grubu oluşturuldu. GEREÇ VE YÖNTEM: Çalışma grubunu fakoemülsifikasyon ile katlanabilir, 5.0 mm, yada 6,5 mm'lik G/M implante edilen 224 olgunun 271 gözü oluşturdu. Bu grubun yaş ortalaması 63.1 ± 11.8 (14-90) idi. Postoperatif 1. gün, 1. hafta ve 1. ay surface regularity index (SRI), surface asymmetry index (SAI), simulated keratometry (SimK1, SimK2) ve minimum keratometrik value (MinK) ortalama değerleri, preoperatif değerlerle karşılaştırıldı. BULGULAR: Sonuçta 6.5 mm GİM'i uygulanan olguların, preoperatif ve postoperatif l.gün SRI değerleri dışında istatistiksel anlamlı fark saptanmadı. GİM uygulanan olguların tümünde postoperatif 1. gün SRI, SAI ortalama değerleri, preoperatif değerlerine göre yüksek iken, postoperatif 1. ayda yaklaşık preoperatif değerler düzeyine düştü. Her üç insizyon tipinde de 1 ay sonunda SimK1, SimK2 ve MinK ortalama değerlerinde istatistiksel olarak anlamlı farklılık saptanmadı. SONUÇ: Operasyon sırasında 6.5mm ye genişletilen tünel insizyonlann korneada kalıcı ciddi astigmatik değişiklikler oluşturmadığı kanısına varıldı.
