Chick feed technique versus standard chop technique in micro incision cataract surgery

Area of Science:

• Ophthalmology
• Surgical Techniques
• Cataract Surgery

Background:

• Reducing corneal incision size is crucial for improving cataract surgery outcomes.
• Smaller incisions lead to less induced astigmatism and faster visual rehabilitation.

Purpose of the Study:

• To compare the efficacy of the chick feed technique versus the standard chop technique in micro incision cataract surgery.
• To evaluate visual recovery and outcomes in patients undergoing phacoemulsification with these two techniques.

Main Methods:

• Analysis of 100 eyes (80 patients) undergoing phacoemulsification via micro incision (1.4-1.6 mm).
• Group I (50 eyes): Standard chop technique. Group II (50 eyes): Chick feed technique.
• All surgeries performed with posterior limbal corneal incision under local anesthesia, with foldable intraocular lens implantation.

Main Results:

• Group II (chick feed) showed significantly faster visual recovery: 80% achieved 6/12-6/9 vision on day one post-op, versus 20% in Group I.
• By the second week, 81% of Group II patients had 6/6 visual acuity, compared to 41.8% in Group I.
• Maximum visual recovery was observed earlier in the post-operative phase for Group II patients.

Conclusions:

• The chick feed technique is a more compromising method for micro incision cataract surgery compared to the standard chop method.
• This is attributed to the chick feed technique's ability to operate effectively with low energy and negligible vacuum.
• The chick feed technique demonstrates superior results in terms of visual recovery speed and final visual acuity.
