[Intraocular lens implantation with one loop haptic amputated: a new propose to the subluxation lens surgical treatment].
OBJECTIVE
To evaluate the postoperative results of congenital lens subluxation corrected by a new technique.


METHODS
Retrospective chart review of 21 eyes of 13 patients with no traumatic lens subluxation who underwent surgery in Altino Ventura Foundation from April, 1999 to April, 2004. The mean age was 8.7 +/- 5.4 years old, and the mean follow-up period was 21.5 +/- 19.3 months. Patients underwent phacoaspiration, endocapsular ring and intraocular lens (IOL) implantation. The implanted IOL had one loop haptic excised and was supported above the ring, inside the capsular bag promoting intraocular lens centralization.


RESULTS
Visual acuity improvement was observed in all cases. There was a significant reduction of the spherical equivalent and spherical component comparing the pre and postoperative refraction (p<0.01). There was no statistically significant difference between the pre and postoperative cylinder component (p=0.71). Posterior capsule opacification was a postoperative complication found in 71.4% of the cases. Early posterior capsulotomy was performed with no complications in these cases.


CONCLUSIONS
Intraocular lens implantation with one loop haptic amputated and supported above the endocapsular ring is an option for the congenital lens subluxation surgical treatment, promoting lens centralization and postoperative visual acuity improvement.
