Abstract

Aims: To describe a new method for scleral fixated intraocular lens (IOL) and to report its long-term follow-up. This study also shows the comparison of the new method with the current popular method that is four flanged scleral fixated IOL. Method: Six patients who underwent the new method (two double flanged IOL) and 6 patients underwent four flanged scleral fixated IOL. Postoperative data was collected and recorded, such as visual acuity, intraocular pressure, anterior chamber activity, sign of IOL decentration/tilting and subjective complaints from the patients. Follow-up was done for 4–8 weeks. Result: Among the first group (two double flanged IOL) the mean visual acuity are 0.28 and 0.34 [uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA)]. The second group (four flanged IOL) the mean visual acuity are 0.29 and 0.35 (UCVA and BCVA). There is no (0%) IOL decentration of both the groups during the follow-up period. No significant anterior chamber reaction was found in both groups. Conclusion: The two double flanged IOL can be used as alternative method for intrascleral IOL fixation. It provides good long-term stabilization, no need for specific IOL, or any hard to obtain material.

Cataract surgery and intraocular lens (IOL) implantation is the most performed operation in the field of ophthalmology
The two double flanged IOL can be used as alternative method for intrascleral IOL fixation
Scleral fixation techniques remain the main choice in the secondary IOL implantation technique [1,2,3,4,5,6]

Summary

Introduction

Cataract surgery and intraocular lens (IOL) implantation is the most performed operation in the field of ophthalmology. Several secondary IOL fixation techniques have been done [1,2,3,4,5,6]. The technique of iris fixation has some disadvantages, such as: distorted pupil, which can make it difficult to evaluate the posterior segment due to undilated pupil, more inflammatory reactions, less stable visual acuity, and refraction. For these reasons, scleral fixation techniques remain the main choice in the secondary IOL implantation technique [1,2,3,4,5,6]
