The Koch endocapsular punch. A report on its use in 96 consecutive cases

Area of Science:

• Ophthalmology
• Surgical Techniques
• Medical Devices

Background:

• Cataract extraction with intraocular lens (IOL) implantation requires precise anterior capsule management.
• Current capsulectomy techniques aim to optimize surgical conditions and IOL positioning.
• A continuous anterior capsulectomy is desirable for reliable IOL centration.

Purpose of the Study:

• To evaluate the efficacy and safety of the Koch endocapsular punch for anterior capsulectomy.
• To assess the impact of the Koch punch on IOL centration and visual outcomes.
• To determine the incidence of complications such as vitreous loss.

Main Methods:

• The Koch endocapsular punch was utilized in 96 consecutive eyes undergoing endocapsular cataract extraction and IOL implantation.
• Surgical outcomes, including IOL centration, vitreous loss, and visual acuity, were assessed.
• Follow-up evaluation included assessment at six months post-surgery.

Main Results:

• Ninety-five out of 96 eyes (99%) demonstrated appropriate IOL centration at the six-month follow-up.
• No instances of vitreous loss were recorded during the surgical procedures.
• Ninety-nine percent of patients achieved a visual acuity of 6/6 or better by six months.

Conclusions:

• The Koch endocapsular punch is a safe and effective instrument for performing anterior capsulectomy.
• This technique facilitates reliable IOL positioning and contributes to excellent visual outcomes in cataract surgery.
• The Koch punch minimizes the risk of intraoperative complications like vitreous loss.
