Purpose:
To describe a flapless technique for two-point fixation of intraocular lens (IOL) with four fenestrated haptics.
Methods:
A transconjunctival puncture of 1-mL syringe needle was used to guide the suture needle out of the eye. The suture was taken out of the eye through the corneal incision, passed through the pair of fenestrated haptics of the IOL and then securely tied with overhand knots. The folded IOL was implanted into the posterior chamber. The anchor knots were created by both ends of the thread approximately 4 mm to 5 mm apart from the transconjunctival puncture and was intrasclerally buried.
Results:
The technique was used in 18 eyes (18 patients). The mean postoperative follow-up period was 17.22 ± 8.82 months. The IOLs of all the eyes remained well positioned and stable at the final follow-up. The visual acuities of all the eyes were improved postoperatively. No suture loosening, suture erosion, hypotony, scleral atrophy, chronic inflammation, retinal tears, and/or detachments were observed in any of the patients.
Conclusion:
The present technique provides minimal trauma and reliable stability for the two-point transscleral fixation of four fenestrated haptics IOL.
