Short-term changes of choroidal vascular structures after phacoemulsification surgery.

Area of Science:

• Ophthalmology
• Vascular Biology
• Medical Imaging

Background:

• Cataract surgery, specifically phacoemulsification, is a common procedure.
• Understanding its impact on choroidal vascular structures is crucial for patient outcomes.
• Previous research has not fully elucidated these vascular changes.

Purpose of the Study:

• To evaluate changes in choroidal vascular structures after phacoemulsification surgery.
• To assess the choroidal vascularity index (CVI) over time post-surgery.
• To identify factors associated with CVI changes.

Main Methods:

• A self-controlled study involving 36 patients undergoing phacoemulsification.
• Enhanced depth imaging optical coherence tomography (EDI-OCT) scans were used.
• Choroidal vascularity index (CVI) was calculated using image binarization.

Main Results:

• CVI significantly increased at 7 days, 1 month, and 3 months post-surgery (p < 0.001).
• A positive association was found between CVI and subfoveal choroidal thickness (SFCT) pre-operation.
• No significant associations were observed with age, axial length, IOP, or gender.

Conclusions:

• Phacoemulsification surgery leads to increased choroidal vascularity in cataract patients.
• Long-term CVI evaluation post-surgery may offer insights into choroidal disorders.
• This study provides valuable data on the vascular effects of cataract surgery.
