SUMMARY

A new technique of posterior chamber IOL implantation is reported in patients without posterior capsule support (Scleral Fixation Technique of Posterior Chamber IOL Implantation).

The authors describe and detail the technique that the IOL loops are fixed in the posterior chamber at 3:00 and 9:00 hours in the sclera 1,0 mm close to the limbus. The aim is to position the loops in the cilliary sulcus.

Using the conventional cataract extraction technique, vitrectomy performed in the anterior chamber and in the anterior vitreous cavity when necessary.

A procedure is descricribed to prevent the IOL tilting, using the microscope light reflex on the IOL body.

22 cases are reported with initial visual acuity ranging from light perception to counting fingers at 3 meters, without optic correction to final results after the surgery ranged from 20/100 to 20/20 and J4 to J1 with optical correction.

The post surgical follow-up were between 3 and 15 months.
