Immediate visual capability after cataract surgery: topical versus retrobulbar anesthesia

Area of Science:

• Ophthalmology
• Surgical Anesthesia
• Vision Science

Background:

• Cataract extraction by phacoemulsification with intraocular lens implantation is a common surgical procedure.
• Anesthesia choice can impact immediate postoperative outcomes and patient experience.
• Evaluating visual acuity and complications is crucial for optimizing surgical techniques.

Purpose of the Study:

• To compare immediate postoperative visual acuity and complication rates between topical and retrobulbar anesthesia in cataract surgery.
• To assess the short-term visual outcomes following phacoemulsification and intraocular lens implantation under different anesthesia types.

Main Methods:

• Prospective evaluation of 56 patients undergoing cataract surgery.
• Comparison of visual acuity (uncorrected and best corrected) at one hour, one day, and one week post-surgery.
• Documentation of complications such as ptosis and diplopia in both anesthesia groups.

Main Results:

• Patients receiving topical anesthesia demonstrated significantly better visual acuity one hour after surgery compared to those under retrobulbar anesthesia.
• No significant differences in visual acuity were observed between the two groups at one day and one week post-surgery.
• Topical anesthesia group experienced no complications, while the retrobulbar anesthesia group reported ptosis and diplopia.

Conclusions:

• Topical anesthesia provides superior immediate visual recovery after cataract surgery.
• Retrobulbar anesthesia is associated with a higher incidence of early postoperative complications like ptosis and diplopia.
• Topical anesthesia is a safe and effective alternative for cataract surgery, promoting faster visual rehabilitation.
