METHODS Retrospective review of 67 eyes of 67 patients with corneal ectasia (64 with keratoconus and 3 with pellucid marginal degeneration) submited to intrastromal corneal ring segments (Keraring R ) implantation, performed by surgeons in training at HOSBOS, using the manual technique. Patients were examined at 1 and 3 months after surgery.

4. No patient had infectious keratitis, bleeding, segment decentration, hydrops or healing defects as described in other studies.

5. CONCLUSIONS The rate and type of intraoperative and postoperative complications of intrastromal corneal ring implantation (Keraring R ), performed by surgeons in training at HOSBOS, using the manual technique, remained within the expected compared to those found in previous studies.
