Brief summary
Toric phakic IOLs are a largely reversible treatment option for patients who are not good candidates for laser refractive surgery and have significant astigmatism. Good alignment of toric IOL is crucial to achieve effective astigmatism correction. One degree of misalignment reduces the astigmatic correction by 3.3%. More than 30 degree of misalignment increasing the amount of preoperative astigmatism. Purpose of our study is to evaluate the accuracy of axis alignment , visual and refractive outcomes after toric phakic Visian toric implantable in patients with astigmatism more than 1.5D. METHODS: this retrospective study investigated toric ICL implantation in 24 eyes of 15 patients . Data were collected one week after toric ICL implantation.
Interventions
toric phakic posterior lens implantation to correct astigmatism done by surgeons who have at least 20 years of experience. The approximate duration of surgery is 10 minutes for each eye. operation was done in the OR of an eye hospital.The current V4C ICL design was used. Under local anesthesia, dilating agents were administered. Preoperative digital reference imaging was obtained by Verion unit. In a temporal approach, after injection of viscoelastic material (Provisc, Alcon), a small 3.2 mm clear corneal incision was made and the ICL was injected through this incision into the anterior chamber and allowed to slowly unfold.After the injection and unfolding of the toric ICL into the anterior chamber, haptics were tucked under the iris. TICL was aligned to the desired axis by the guide of VERION digital marking.
