Abstract Details

Purpose:

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

Setting:

Eye Clinic University Medical Center ″ Zvezdara″, Belgrade

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 47 eyes of 47 patients (55% females, from 21 to 81 years) were operated and postoperatively followed with a mean time of 19.2+3.4 weeks. Two different three-piece lens designs were inserted. Improvement in visual acuity was registered in all eyes with a mean BCVA of 0.23+0.08 logMAR at the end of the follow up. Mean spherical equivalent was - 1.17± 1.45 D and median astigmatic error was -1.25 D cylinder (range from 0.5 to 1.75). Mean lens tilt was 3.2º ±2.4º. Early postoperative complications were vitreous haemorrhage in 4.25%, transient intraocular pressure elevation at 2.12% and corneal oedema at 4.25%.

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 minimally invasive method for achieving good IOL stability, also gives excellent postoperative visual outcomes.
