| Summary: | <b>AIM:</b> To explore a simple and low-cost self-made disposable flexible iris retractor and study its clinical efficacy and safety in small pupil phacoemulsification.
<b>METHODS:</b> Polyproplyene suture and scalp acupuncture were used to make iris retractor. A prospective study were carried on 50 patients (50 eyes) with a maximally dilated pupil size of 2.5-4.0 mm which underwent phacoemulsification using this self-made iris retractor. Another 50 cases of phacoemulsification with normal pupil size sever as control group. The mean operation time, ultrasound time and ultrasonic power, volume of irrigation fluid were documented intraoperatively. The visual acuity, pupil size and complication were observed on 1d, 1wk, 1mo and 1y after operation. Corneal endothelial cell was measured at 1mo postoperatively.
<b>RESULT:</b> Pupils could be expanded to approximately 4.5-5.5 mm with our self-made iris retractor in operation. No serious postoperative complication was found. Most (88%) of the pupils returned round or oval shape, light reflex restored to varying degrees at the first day after surgery. Best corrected visual acuity stabilized in 37 eyes (74%) at one day, in 43 eyes (86%) at one week, in 44 eyes (88%) at one month and 46 eyes (92%) at one year. Compared with the control, more time was needed to complete the operation in the small pupil group. There was no significant difference of the mean ultrasound time, ultrasonic power, volume of irrigation fluid required and corneal endothelial cell loss in 1mo follow up between the two groups.
<b>CONCLUSION:</b> Our self-made disposable flexible iris retractor could be easy obtained preoperatively or intraoperatively. It performed both safety and efficacy in our clinical trials. This simple self-made device has shown economic and practical values, especially in primary care hospital of the less developed districts. |
