[Unfolded intraocular lens implantation through a 6 mm sutureless incision]
Objective:
To evaluate the therapeuitic effects of phacoemusification and unfolded iutraoculavr lens (IOL) implantation through a 6 mm sutureless incision.
Methods:
A 6 mm sclera tunnel incision was made at 12 o'clock tangent of the posterior limbus and unfolded polymethylmethacrylate(PMMA) IOL implantation was operated in 50 cases (55 eyes); 53 eyes were finished without suture after phacoemusification and 2 eyes were done with extra capsule cataract extration(ECCE) because of the broken posterior capsular.
Results:
Postoperatively, the visual acuity was 0.6 or more in 92.4% of the eyes and 1.0 or more in 50.9% of the eyes at one week; 0.6 or more in 98.1% of the eyes and 1.0 or more in 67.9% of the eyes at one month. The mean postoperative astigmatism was 0.63 +/- 0.36 D at one week and 0.61 +/- 0.33 D at one month. There was no statistical difference between the mean preoperative astigmatism(0.60 +/- 0.48 D) and postoperative astigmatism at one week and one month (P > 0.05).
Conclusion:
The technique of phacoemusification and PMMA IOL implantation through a 6 mm sutureless incision can reduce early postoperative astigmatism, shorten the period of visual rehabilitation.
