Abstract
Background: Cataract is the most cause of blindness in the world. Cataract treatment is surgery (Phacoemulsification) with intraocular lens (IOL) implantation in bag. Scleral fixation of intraocular lens (some situation), the haptic of IOL normally sutured with the sclera. This study collected the data from patients who operated special technique, flanged intrascleral intraocular lens fixation (F-IOL) and Four-flanged intrascleral intraocular lens fixation (FF-IOL), the technique using cauterization for fixing IOL to the sclera.
Objective: To propose and determine the operation, clinical outcomes and safety of flanged intrascleral intraocular lens fixation and Four-flanged intrascleral intraocular lens fixation.
Methods: collect data of patient operated using flanged intrascleral intraocular lens fixation or Four-flanged intrascleral intraocular lens fixation (FF-IOL) techniques. Preoperative demographic data, best-corrected visual acuity (BCVA), diagnosis, operation, operation time and complications were collected. compare of two operation techniques.
Results: Twenty eyes from 20 patients were reviewed. After surgery, mean BCVA improved to 0.63 logMAR, in flanged intrascleral intraocular lens fixation technique mean BCVA improve to 0.53 logMAR and in four-Flanged intrascleral intraocular lens fixation mean BCVA improve to 0.7 logMAR ,the visual acuity mean improve 25 letter score (mean visual gain 30 letter in flanged intrascleral intraocular lens fixation technique and 20 letter in four-Flanged intrascleral intraocular lens fixation ).The mean operation time is 43.8 (15.7) minutes (48.6 in four-Flanged intrascleral intraocular lens fixation and 41.2 flanged intrascleral intraocular lens fixation technique). 3 cases of corneal edema , 1 Acute PO hypotony, 1 IOL decentration/ 1 IOL tilt, 1 pseudophakic bullous keratopathy were observed in this study.
Conclusion: Flanged intrascleral intraocular lens fixation and four-Flanged intrascleral intraocular lens fixation technique resulted in good visual outcome and safe for IOL implantation in any eye condition imposible to implant the IOL in normal capsular bag.
