What are capsulorhexis pliers?

Capsulorhexis pliers are a surgical tool used to remove the front lens of the eye during the cataract operation. The tool is shaped as tweezers or pliers, but with sharp tips. These tips are used to cut the eye surface and create a valve so that the surgeon can remove the damaged part of the eye. The sharp tips used for cut and to grip the lens are slightly curved and only half an inch (13 mm) from bend to tip. The pliers could be made of titanium or stainless steel and sterilized for multiple uses, or capsulorhexis pliers can be purchased as a single use with a disposable tool with a plastic handle.

capsulorhexis is a form of capsulotomy in which the cut is carried out along the periphery of the lens in a smooth circle. This is also known as continuous curved capsulorhexis (CCC). The cut into the center -dollar capsule is created using sharp tip of capsulorhexis pliers. The surgeon then continues to cut either clockwise or counterclockwise around the nitroEye lenses. The tips of the pliers are then used to tow part of the tissue, create a flap, then grip and place an artificial lens, which will replace the removed cataract.

Many capsulorhexis pliers include a ruler reached at the top of the instrument shaft to determine the capsulorhexis cut diameter. The tips can be serrated for optimal tissue and lenses. The pliers handle can include combs or indentation for more stable adhesion of the surgeon.

Inhabitants and beginners of ophthalmological surgeons could consider using capsulorhexis pliers, so there is also an alternative tool known as cystitom or cystotom. The deputystitom, which has two sharp points to create a cut, is a small knife with a single curved or dependent blade. Cystitom has a smaller diameter than capsulorhexis pliers, so there is less risk of creating too much cut.
