Phacoemulsification through a small pupil

OBJECTIVE: To discuss the surgical techniques and attention points in phacoemulsification through a small pupil. METHOD: Eighty three cataracts of 77 patients were emulsified by using non-cut pupil dilation, cystotome or diathermic high-frequency capsulorrhexis. RESULTS: The 66 cataracts of 83 eyes were emulsified by means of the above method. After the surgery, all the pupils were recovered to normal size (2 to 3 mm), and none of them were damaged. In 17 eyes, the procedure was performed after separation of synechia and excision of the organized membranes; after the surgery, a round pupil was obtained in 15 cases and an irregular pupil in 2 cases. The visual acuity at postoperative 1 month was >or= 0.5 in 46 eyes (55.4%) and corrected >or= 0.5 in 71 eyes (85.5%). CONCLUSION: After phacoemulsification through a small pupil by non-cut pupil dilation method, the pupil can be recovered to normal and no unfavorable reaction is seen.
