This study shows the miCOR 700 lens extractor is a safe and effective tool for cataract surgery, with improved efficiency as surgeons gain experience. Visual acuity improved post-surgery.

Area of Science:

  • Ophthalmology
  • Surgical Innovation

Background:

  • Cataract surgery is a common procedure.
  • New surgical devices aim to improve efficiency and patient outcomes.

Purpose of the Study:

  • Evaluate the initial surgical experience and learning curve with the miCOR 700 lens extractor.
  • Assess the device's safety, efficacy, and impact on surgical time and visual outcomes.

Main Methods:

  • Retrospective analysis of 61 cataract surgeries using the miCOR 700 lens extractor.
  • Data collected included surgical times, complications, corrected distance visual acuity (CDVA), intraocular pressure (IOP), and pachymetry.
  • Regression analysis was used to evaluate the learning curve and factors influencing surgical outcomes.

Main Results:

  • Surgical experience significantly reduced procedure, nuclear removal, and cortex removal times.
  • Higher nuclear density correlated with longer procedure and nuclear removal times.
  • Postoperative CDVA improved significantly; no thermal damage or device-attributed complications were noted.

Conclusions:

  • The miCOR 700 lens extractor is an innovative and cost-effective option for cataract surgery.
  • Further comparative studies with conventional phacoemulsification are warranted.
