AIM: To evaluate the efficacy and safety of implantation of phakic posterior chamber intraocular lens for high myopia by a single incision.

METHODS: Phakic posterior chamber intraocular lens implantation surgery by a single incision was performed in 9 patients(18 eyes)with high myopia. All patients were followed up for 3 to 9 months to record the clinical ocular data including uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), diopter, astigmatism, intraocular pressure, the number of endothelial cell etc. before and after surgery.

RESULTS: Phakic posterior chamber intraocular lens were implanted successfully in all the operative eyes. The mean preoperative diopter was(-13.38±-5.32)D, and postoperative diopter was(-0.25±0.38)D. All eyes of the preoperative and postoperative uncorrected visual acuity(UCVA)and the best corrected visual acuity(BCVA)were 0.06±0.04, 0.6±0.2, 0.5±0.2, 0.7±0.3 respectively. It was obvious that postoperative UCVA and BCVA were better than the preoperative UCVA and BCVA(P<0.05). The mean preoperative and postoperative IOP was(13.23±3.18)mmHg,(15.03±1.25)mmHg, respectively. The cornea endothelial cell density was(3008±298)/mm² before operation and(2896±246)/mm² after operation; average preoperative anterior chamber depth was(3.56±0.29)mm; postoperative anterior chamber depth was(3.68±0.37)mm; preoperative corneal astigmatism was(0.52±0.30)D and postoperative refractive cylinder was(0.67±0.45)D, showing no statistical differences(P>0.05).

CONCLUSION: Phakic posterior chamber intraocular lens implantation for high myopia by a single incision is a reliable and effective method with low risk, small ocular surface injury, low cost and small astigmatism induced by surgery. It can be a suitable operation method.
