[Original technique of double capsulorhexis]

Area of Science:

• Ophthalmology
• Surgical Techniques
• Intraocular Lenses

Context:

• Current endophako techniques with posterior scleral tunnel incisions necessitate precise capsulorhexis.
• Capsulorhexis ring rupture can lead to posterior capsular tears.
• Excessive anterior capsular residue may cause purse-string fibrosis.

Purpose:

• To introduce and evaluate the double circular capsulorhexis technique.
• To address complications associated with standard capsulorhexis in endophako surgery.
• To improve surgical reproducibility and long-term outcomes.

Summary:

• The double capsulorhexis technique involves creating a small initial capsulorhexis (approx. 4mm) and a second one post-operatively.
• This technique enhances safety during surgery, even in challenging cases like hypertonia or poor visibility.
• It prevents anterior capsular edge tears and mitigates purse-string fibrosis by guiding healing.

Impact:

• Offers improved safety and reproducibility during cataract surgery.
• Reduces the incidence of posterior capsular tears and anterior capsular fibrosis.
• Facilitates better long-term retinal follow-up by managing capsular residue.
