Visual function recovery after phacoemulsification is relatively slow initially but improves significantly within 4 hours. This suggests early patient discharge following cataract surgery with topical anesthesia is generally safe.

Area of Science:

  • Ophthalmology
  • Surgical Outcomes

Background:

  • Phacoemulsification is a common cataract surgery technique.
  • Topical anesthesia is frequently used for patient comfort and safety.

Purpose of the Study:

  • To evaluate the speed of visual function recovery after phacoemulsification performed with topical anesthesia.
  • To determine the safety of early patient discharge post-surgery.

Main Methods:

  • Prospective study of 20 patients undergoing sutureless clear corneal phacoemulsification.
  • Assessment of visual acuity (LogMAR) and contrast sensitivity (Pelli-Robson) at 1, 2, 4, and 16 hours postoperatively.
  • Postoperative examination at 1 week.

Main Results:

  • Visual acuity improved to a mean LogMAR of 0.425 (6/15) by 4 hours and 0.165 (6/9.5) by 16 hours.

  • No instances of postoperative ptosis or diplopia were reported.
  • Initial visual recovery was slow in the first 2 hours.

    • Conclusions:

    • Rapid visual function return by 4 hours (mean acuity 6/15) supports the safety of early discharge.
    • The absence of diplopia and ptosis further indicates a favorable early recovery profile.
    • Phacoemulsification with topical anesthesia allows for timely visual rehabilitation.
