AIM: To evaluate the clinical significance and technique of intraocular lens implantation in the condition of vitreous cavity filled with gas.

METHODS: Clinical data of 36 patients(36 eyes)who received intraocular lens implantation in the condition of vitreous cavity filled with gas was retrospectively studied. The postoperative follow-up period was for 3-12 months, averaged in 5.6 months.

RESULTS: Postoperative visual activity improved 2-6 lines compared with preoperative best corrected visual activity in all eyes. No severe complication occurred.

CONCLUSION: Assisted with noncontact panoramic viewing systems, it is easier to observe peripheral retinal clearly for photocoagulation in aphakia with gas filled vitreous cavity. Intraocular lens implantation in the condition of vitreous cavity filled with gas is easier, without unnecessary duplication operation. The surgery is safe and effective without too much difficulty.
