Abstract Details

Purpose:

We attempted to introduce a sulcus-fixation technique of standard capsular tension ring in cataract surgery to stabilize the lens capsule.

Setting:

Tertiary referral hospital

Methods:

15 eyes, where the unstable lens capsule or lens subluxation was associated in patients with Marfan syndrome or previous trauma, were included. A standard capsular tension ring anchored with a 10-0 prolene suture was inserted in the bag. After the implantation of intraocular lens in the bag, the capsular tension ring was sulcus-fixated at the 2-3mm posterior to the limbus using the 10-0 prolene suture to stabilize the lens capsule. The best-corrected visual acuity (BCVA) and refraction were measured and the IOL position was checked with a slit lamp biomicroscopy after dilation preoperatively and at one and six months postoperatively.

Results:

The BCVA (logMAR) were 0.36±0.28, 0.21±0.39, and 0.17±0.15 preoperatively and 1 and 6 months postoperatively, respectively. The spherical equivalents (D) was -4.64±6.64, -0.15±2.10, and 0.30±2.15 preoperatively and 1 and 6 months postoperatively, respectively. The BCVA at 1 and 6 months postoperatively was significantly higher than that prior to surgery (P <0.05). The positions of all inserted IOLs were stable.

Conclusions:

In cataract surgery associated with the unstable lens capsule or crystalline lens subluxation, the sulcus-fixated standard capsular tension ring seemed to be a helpful technique to stabilize lens capsule.
