Inflammatory response after endocapsular phacoemulsification or conventional extracapsular lens extraction in the...

Area of Science:

• Ophthalmology
• Surgical Innovation
• Inflammatory Response

Background:

• Cataract surgery involves lens extraction and intraocular lens (IOL) implantation.
• Phacoemulsification and extracapsular lens extraction are common surgical techniques.
• Understanding the inflammatory response is crucial for patient outcomes.

Purpose of the Study:

• To compare the inflammatory response between phacoemulsification and conventional extracapsular lens extraction.
• To evaluate surgical trauma and blood-aqueous barrier integrity after different cataract surgery methods.

Main Methods:

• Phacoemulsification performed on one eye and extracapsular lens extraction on the fellow eye in New Zealand albino rabbits.
• Polymethylmethacrylate IOL implantation and wound closure with 9-0 polypropylene suture.
• Measurement of prostaglandin E2, iris-ciliary body wet mass, white blood cells, protein levels, and corneal thickness at various time points.

Main Results:

• Extracapsular lens extraction led to significantly higher prostaglandin E2 levels and iris-ciliary body wet mass.
• Phacoemulsification resulted in lower white blood cell counts and protein levels in aqueous humor.
• Extracapsular lens extraction induced more significant corneal edema post-surgery.

Conclusions:

• Phacoemulsification demonstrates a reduced inflammatory response compared to extracapsular lens extraction.
• Phacoemulsification appears to cause less surgical trauma and preserves blood-aqueous barrier integrity more effectively.
• These findings support phacoemulsification as a preferred method for cataract surgery due to its milder inflammatory profile.
