Summary
Phacoemulsification can cause retinal thickening and macular edema, especially with higher phaco power. Visual outcomes correlate with the degree of macular thickening after cataract surgery.
Area of Science:
- Ophthalmology
- Retinal imaging
- Cataract surgery
Context:
- Senile cataract affects visual acuity.
- Phacoemulsification is a common cataract surgery technique.
- Optical coherence tomography (OCT) is crucial for macular assessment.
Purpose:
- To investigate the impact of uncomplicated phacoemulsification on the macula using OCT.
- To compare pre- and post-operative retinal thickness and visual acuity.
Summary:
- Post-surgery, 80 eyes showed no significant change in mean foveal thickness, though three developed macular edema.
- Higher phaco power correlated with increased retinal thickness and inflammation (P < 0.05).
- Visual acuity after surgery negatively correlated with retinal thickness.
Impact:
- Uncomplicated phacoemulsification can lead to retinal thickening and macular edema.
- Higher phaco power increases inflammation and retinal thickness.
- Macular thickening directly impacts visual outcomes post-cataract surgery.
