Summary
This study introduces a simple hydro-dispersion technique using balanced salt solution (BSS) to remove difficult subincisional cortex during cataract surgery. The method proved safe and effective in 93.3% of cases, simplifying a challenging aspect of the procedure.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Cataract Surgery
Background:
- Subincisional cortex removal can be challenging in cataract surgery.
- Standard irrigation/aspiration devices may struggle with residual cortical material.
- A novel technique is needed to address this surgical difficulty.
Purpose of the Study:
- To present a simple technique for facilitating the removal of subincisional cortex.
- To evaluate the efficacy and safety of the hydro-dispersion technique.
- To offer an alternative method for managing difficult cortical remnants.
Main Methods:
- A 27-gauge blunt needle attached to a syringe with balanced salt solution (BSS) was used.
- BSS was flushed into the anterior chamber to disperse subincisional cortex.
- The loosened cortex was then removed using coaxial irrigation/aspiration.
Main Results:
- The technique was applied to 60 eyes experiencing difficulty with subincisional cortex removal.
- Successful removal of subincisional cortical material was achieved in 93.3% (56/60 eyes).
- No intraoperative or postoperative complications were reported.
Conclusions:
- The hydro-dispersion technique is a simple and safe method for removing difficult subincisional cortical material.
- This approach offers an effective solution when standard coaxial irrigation/aspiration is insufficient.
- The technique enhances the management of residual cortex in cataract surgery.
