Area of Science:

Ophthalmology
Surgical Techniques
Intraocular Lenses

Background:

No financial or proprietary interests were disclosed by the authors.
Standard surgical practices in ophthalmology.

Purpose of the Study:

To describe a modified capsular tension ring (CTR) insertion technique.
To improve upon the existing fishtail technique for CTR insertion.
To minimize risks associated with CTR implantation.

Main Methods:

A novel technique for capsular tension ring (CTR) insertion is detailed.
A suture line is utilized to guide the leading eyelet through the main incision.
The CTR is not dialed into the capsular bag, similar to the fishtail technique.

Main Results:

The described technique forms a 'fish' configuration for CTR insertion.
This method reduces the risk of zonular damage and capsule tears.
The suture prevents over-bending of the CTR during insertion, a potential issue with the traditional fishtail technique.

Conclusions:

The modified CTR insertion technique offers a safer alternative for ophthalmic surgeons.
This technique enhances the safety profile of capsular tension ring implantation.
It provides an advantage over the traditional fishtail technique by preventing CTR over-bending.
