Intraocular lens optic capture in eyes with zonular weakness in cataract patients

Abstract

We desribe a technique for managing cataracts in eyes with zonular weakness. The technique is a combination of microhook iris retractors to fixate the capsulorhexis, a capsular tension ring, and intraocular lens optic capture. Results of this technique in 70 eyes after a 13-month mean follow-up are reported.

Outcome of phacoemulsification and intraocular lens implantion in eyes with pseudoexfoliation and weak zonules

“…; Devranoğlu et al. ; Wang et al. ), but reports on the postoperative outcome of CTR implantation in PEX eyes are scarce.…”

“…Intraocular lens (IOL) capture, with the optic in the capsular bag and haptics in the sulcus, can also be used with these types of IOLs to further enhance IOL positional stability (Devranoğlu et al. ). In PEX eyes with vitreous loss and minimal capsular support, we favour placement of a scleral or iris‐fixated three‐piece PC‐IOL or AC‐IOL.…”

Pathologic evidence of pseudoexfoliation in cases of in-the-bag intraocular lens subluxation or dislocation

“…10 Standard CTRs do not prevent capsulorhexis phimosis or late dislocation. 8 38 describes a promising surgical technique to prevent late in-the-bag dislocation in at-risk patients. The technique is based on the combined effect of multiple historical methods to maximize IOL and capsular bag stabilization during and after surgery.…”

Management of the subluxated crystalline lens: A review

“…In addition, in cases of microspherophakia, the haptics are compressed closer to the optic without excessive stress on the capsular bag. Other surgeons prefer to place the CTR in the bag and a 3‐piece IOL in the sulcus with optic capture, 17 inducing less zonular stress.…”

“…They may be latched onto the capsulorhexis rim to provide countertraction during capsulorhexis 12,37 in severe zonulysis. In addition, they may be used to provide anteroposterior capsular bag support 17 . However, these hooks do not support the lens equator as the ends are short unless used in combination with a capsular tension segment (CTS) or CTR.…”
