Focus on Capsular Tension Rings

STABILEYES
AMO

The newest FDA-approved capsular tension ring (CTR) is the StabilEyes. This circular device, which is available in 12-mm and 13-mm diameters, provides capsular bag support in cataract patients with weak zonules. Once in place, the StabilEyes CTR reduces the risk of capsular fibrosis and capsular shrinking.

While operating on cataract patients with especially weak zonules, Richard Mackool, M.D., recognized the need for a special instrument to stabilize the capsular margins during phaco. The result is his Cataract Support System, a specialized retractor that features angles compatible with the plane of the anterior capsule and a 1.5-mm hook return. In addition to maintaining capsule position during phaco, this system helps you avoid the problem of the ring trapping cortex and prevent zonular stress during nuclear rotation. This system is approved by the FDA.

Iqbal Ahmed, M.D., has developed a capsular tension segment (CTS) that effectively supports the capsule, even in the presence of capsular tears, without causing additional zonular damage. This device, which features a fixation hook similar to that on the Cionni Modified Capsular Tension Ring, has no sharp points to tear the capsulorhexis. Surgeons can use one or more segments to support the capsule temporarily or permanently. The Ahmed CTS is still awaiting FDA approval.

MORCHER CAPSULAR TENSION RING
FCI Ophthalmics

The Morcher Capsular Tension Ring (CTR), which comes in 12.3-mm, 13-mm and 14.5-mm diameters, was the first to receive FDA approval for ophthalmic use in the United States. This PMMA ring supports weak zonules during cataract surgery, centering the capsular bag and providing greater access to the cataract. Surgeons can insert this CTR manually using a Sinskey hook and forceps, or by using a Geuder injector, which facilitates proper and smooth placement by dialing the ring into the capsular bag. Advantages of the Morcher CTR include better IOL centration and overall capsule stability.

CIONNI MODIFIED CAPSULAR TENSION RING
Morcher

Patients who have significant zonular dialysis or marked capsular decentration often need more support than that offered by basic capsular tension rings (CTRs). To overcome this problem, Robert J. Cionni, M.D., added a horseshoe-shaped fixation hook about 0.25 mm above the tension ring plane. He uses this ring to immobilize the CTR by anchoring the fixation hook to the scleral wall with sutures. Use of the Cionni Modified CTR is limited to patients with intact capsulorhexes and posterior capsules. This device is still awaiting FDA approval for ophthalmic use in the United States.
