Summary

Simultaneous vitrectomy and cataract surgery can cause a myopic shift, especially when gas tamponade is used. This gas may push the intraocular lens forward, affecting refractive outcomes.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Refractive Surgery

Background:

  • Cataract surgery aims for precise refractive outcomes.
  • Vitrectomy is often combined with cataract surgery for various retinal conditions.
  • Understanding refractive predictability after combined procedures is crucial.

Purpose of the Study:

  • To evaluate the impact of vitrectomy on postoperative refractive error.
  • To compare refractive outcomes between combined surgery and cataract surgery alone.
  • To analyze the influence of gas tamponade on refractive outcomes.

Main Methods:

  • Retrospective analysis of 206 eyes undergoing combined vitrectomy and cataract surgery.
  • Comparison with 67 eyes undergoing cataract surgery only.

  • Analysis of refractive outcomes based on the presence or absence of gas tamponade.

    • Main Results:

    • Combined surgery group showed a mean refractive shift of -0.05 D versus +0.55 D in the control group.
    • Eyes with gas tamponade experienced a greater myopic shift (-0.36 D) compared to those without (-0.14 D).
    • Refractive outcomes in the combined surgery group shifted towards myopia.

    Conclusions:

    • Combined vitrectomy and cataract surgery can lead to myopic shifts.
    • Gas tamponade in combined procedures exacerbates myopic progression.
    • Gas tamponade may induce anterior displacement of the intraocular lens.
