PRESBYOND can occasionally be performed after vitrectomy surgery, but suitability depends heavily on retinal recovery and visual potential.
Challenges after vitrectomy
Posterior segment disease often dominates vision.
- Vitrectomy is typically performed for macular holes, detachments, or haemorrhage
- These underlying conditions may permanently limit acuity or contrast
- Corneal laser cannot correct residual retinal distortion or scarring
- Blended‑vision optics may be less well tolerated in compromised eyes
- Overall risk-benefit balance must consider previous surgery and prognosis
Situations where it might be reasonable
Only if the eye retains strong potential.
- Stable post‑vitrectomy retina with good central vision
- Clear cornea and lens, with presbyopia as the main problem
- Retinal surgeon agrees vision is robust enough for refractive surgery
- Patient understands that laser will not fix any remaining retinal issues
- All alternatives are discussed before proceeding
