Objectives : To evaluate the result of a surgical technique to insert and secure a standard posterior chamber
lens through a simple limbal incision in eyes that had no capsular support or whose capsule was inadvertently
ruptured during extracapsular cataract extraction.
Materials and Methods : Retrospective review of the medical records of patients who underwent translimbal
fixation of posterior chamber lenses according to age, gender, preoperative visual acuity, postoperative
visual acuity, follow-up period and any complications, especially those that may be related to the surgical
technique.
Results : Twelve patients were recruited in the present study. The patentsûage ranged from 31 to 77 years, with
a mean of 62.58 years. There were 9 male and 3 female patients. The preoperative visual acuity ranged from
hand motion to counting fingers, and the postoperative visual acuity ranged from 6/6 to 6/24 except one
patient who had postoperative visual acuity of counting fingers due to a pre-existing macular hole. The length
of follow-up period ranged from 3 to 12 months, with a mean of 6.17 months. There was no clinically significant
lens-related complication.
Conclusion : This simple surgical technique controls the location of the needle entry and exit to decrease the
risk of bleeding and increase the chance of ciliary sulcus placement. An inferior groove was made to bury the
suture knot and was sutured closed to prevent the knot erosion through the conjunctiva.
