Refraction and Anterior Chamber Depth Change After Vitrectomy for Pseudophakia

Epiretinal membrane surgery: an analysis of 2‐step sequential‐ or combined phacovitrectomy surgery on refraction and macular anatomy in a prospective trial

“…The refractive change in pseudophakic eyes following vitrectomy for various vitreoretinal pathologies has been found to vary between À0.15 and À0.84 D (Campo et al 1999;Kumagai et al 2001;Sharma et al 2005;Byrne et al 2008). However, these studies also included eyes with intraocular gas tamponade.…”

Choice of intraocular lens may not affect refractive stability following cataract surgery

“…In addition, refractive error may not be stable and thus it may differ immediately post‐procedure from that weeks or months later 25 . Similarly, this may be affected by wound type 9 , IOL selection 26,27 or subsequent procedures 28–30 .…”

Refractive change after vitrectomy for epiretinal membrane in pseudophakic eyes

“…Studies including various vitreoretinal pathologies found refractive changes between )0.30 (Kumagai et al 2001) and )0.45 D (Byrne et al 2008) in pseudophakic vitrectomy. These studies also included patients with intraocular gas tamponade.…”

“…In pseudophakic eyes that achieved emmetropia following cataract surgery, it is important that subsequent vitrectomy does not result in major changes in refraction. Reports have found changes in refraction toward myopia in pseudophakic eyes undergoing vitrectomy for various pathologies (Campo et al 1999;Kumagai et al 2001;Byrne et al 2008). Several explanations have been suggested for the observed refractive change, including changes in the effec-tive lens plane (ELP), that is, the position of the IOL, and the axial length (AL).…”
