AIM:To investigate the application of suture fixation of intraocular lens(IOL)implantion in posterior chamber in the following cases:posterior capsule broken in extracapsular cataract extration,injury cataract,lens dislocation and post eperative vitrectomy.METHODS:From April 2010 to April 2011,24 cases(24 eyes) used ciliary groove suture with posterior chamber type of intraocular lens and all cases acquired satisfied result.In 7 cases with two remaining quadrants posterior capsule due to lens posterior capsule damage,relying on the remaining posterior capsule,one side of the IOL loop was placed on it,the other side of the loop were implemented ciliary groove suture fixation,which was "one point fixation".Severe post-traumatic 17 cases without lens posterior capsule were implemented the ciliary groove suture fixation of both sides loops,which was "two-point fixation".RESULTS:Following up for 4-12 months(average 6 months),the BCVA was from 0.01 to 1.2 and 15 eyes’ vision were more than 0.6(62.5%).Poor vision was because of the corneal scar and injury fundal diseases.Transplanting the IOL secondarily made the vision better than pre-operation best-corrected visual acuity(BCVA).The intraocular pressure(IOP) in all eyes were normal and all had no complication.CONCLUSION:The method of suture fixation of intraocular lens implantion in posterior chamber is the best select to the lens with the posterior capsule broken or disappearance and large range ligaments loose.
