[Extra-capsular cataract extraction and intraocular lens implantation in cases with cataract and a small pupil with synechiae].
OBJECTIVE
To introduce a new surgical technique for cataract with a small synechia pupil and evaluate its effects.


METHODS
43 eyes of 40 patients were operated on and followed up for 3-30 months. Surgical procedures included iridectomy, separating the posterior synechiae, straight cutting of upper iris and making 3 little cuts at inferior pupillary margin, extracapsular cataract extraction, intraocular lens implantation, and at last suturing the iris cuts to form a round pupil.


RESULTS
Postoperatively, all 43 eyes had 3-4 mm basically round pupil and 42 eyes (97.7%) had improved vision. Of the 32 eyes followed up for more than three months, 22 eyes (68.8%) obtained visual acuities 0.5 or better, 10 eyes (31.2%) had visual acuities worse than 0.4 which were attributed to posterior segment abnormalities. Intraoperatively, no posterior capsular rupture was seen, and postoperatively, no severe complications were found.


CONCLUSIONS
The results suggest that patients with cataract and a small synechia pupil obtain improved vision and round pupil without unacceptable risk by means of the surgical technique mentioned in this paper.
