Abstract Details

Purpose:

To report and evaluate outcomes of the double-needle technique for flanged intrascleral posterior chamber intraocular lens (IOL) fixation.

Setting:

Clinic for Eye Disease  Prof. dr Ivan Stankovic University Medical Center Zvezdara

Methods:

Aphakic eyes with absence of adequate capsular support underwent a surgical procedure of flanged intrascleral posterior chamber intraocular lens fixation, the technique that involves externalization of IOL haptics using double 30 gauge needles. A flange was created at the end of each haptic that were then fixed into the scleral tunnel. Two  different three-piece lens designs were inserted.  Patients were followed up postoperatively and main outcome measures were monitored: best-corrected visual acuity (BCVA) converted to the logarithm of the minimum angle of resolution (logMAR), final mean refractive error (spherical equivalent and astigmatism), and intra- and post-operative complications.

Results:

Overall 28 eyes of 28 patients (55% females, from 25 to 63 years) were operated and postoperatively followed with a mean time of 16.8+3.6 weeks. Two different three-piece lens designs were inserted. Improvement in visual acuity was registered in all eyes with a mean BCVA of 0.26+0.09 logMAR at the end of the follow up. Mean spherical equivalent was  1.24 ± 1.50 D and median astigmatic error was -1.25 D cylinder (range from 0.5 to 2D). Mean lens tilt was 2.87±2.19 degrees. Early postoperative complications were vitreous haemorrhage at 0.84%, intraocular pressure elevation at 1.12% and corneal oedema at 1.4%.

Conclusions:

No intraoperative complications were registered and postoperatively all IOLs remained stable and well centered. None of the eyes had scleral necrosis, cistoid macular edema, retinal detachment or endophthalmitis. The double-needle technique is an elegant technique for IOL fixation. It is a simple and minimally invasive method for achieving good IOL and haptic fixation and also excellent postoperative visual results
