Visual Outcomes and Safety of a Small Diameter Intrastromal Refractive Inlay for the Corneal Compensation of Presbyopia

Abstract

The intracorneal refractive inlay (Invue Lens) seems to be an effective surgical method for the corneal compensation of presbyopia in emmetropes aged between 45 and 60 years.

Femtosecond Laser-Assisted Intracorneal Biopolymer Insertion for the Symptomatic Treatment of Bullous Keratopathy

“…10 This has been a concern also for the implantation of intracorneal inlays for the corneal compensation of presbyopia. 10,11 In our cases, we created an intracorneal pocket of 6.5 mm in diameter (about half the diameter of the cornea) in which we injected silicone oil (barrier); this approach leaves the peripheral corneal (outside the 6.5 mm) intact, and thereby the transport of glucose at the anterior cornea although influenced, it is not completely stopped, which allowed for suboptimal corneal nutrition.…”

Prise en charge de patients hypermétropes presbytes par chirurgie cornéenne de type presbylasik centré

“…L'approche cornéenne est séduisante car elle présente un minimum de risques, particulièrement en comparaison à la chirurgie endoculaire (risque d'endophtalmie aiguë sur un oeil parfaitement voyant). Il existe à ce jour plusieurs techniques de chirurgie cornéenne proposées aux patients presbytes : la monovision ou « bascule », les inlays intracornéens, l'intracor (intrastromal femtosecond treatment) et le presbylasik [2][3][4][5][6][7][8][9][10][11][12][13][14]. Ce dernier se divise en deux techniques capables de réaliser « une cornée multifocale » par chirurgie réfractive cornéenne.…”

Intracorneal Refractive Surgery: Lenses and Ring Segments

“…Invue lens (Biovision) is another corneal inlay which is implanted inside a corneal pocket of the nondominant eye created using a mechanical microkeratome. Bouzoukis et al [10] reported improving near visual acuity with 20/32 UNVA in 98% of the patients.…”

“…Compared to the mechanical technique, the FS laser makes tunnel creation faster, easier and more reproducible and offers precise tunnel dimensions (width, diameter and depth) compared to manual techniques [7][8][9][10][11][12][13][14][15]. Thus, FS-assisted intracorneal pocket creation could increase the precision of the inlay position and result in better final visual outcomes besides improving the safety of the procedure.…”

“…Lamellar flaps and intrastromal pockets for intracorneal inlay insertion can both be created with mechanical microkeratomes [10,12,13] or using an FS laser technology [14,15]. Compared to the mechanical technique, the FS laser makes tunnel creation faster, easier and more reproducible and offers precise tunnel dimensions (width, diameter and depth) compared to manual techniques [7][8][9][10][11][12][13][14][15].…”
