KEY CONCEPTS • Corneal regeneration is a new approach in corneal surgical technique based on advanced therapies using stem cell therapy and bioengineering. In the future, the combination of both…
KEY CONCEPTS • Bowman’s layer transplantation can be used for the treatment of patients with advanced keratoconus not eligible for corneal cross-linking or intrastromal corneal ring segments, effecting a reshaping…
KEY CONCEPTS • Cataract surgery in the keratoconus patient is challenging. Difficulties in determining accurate measurements for intraocular lens calculations in advanced cases can lead to inaccurate and unpredictable results….
KEY CONCEPTS • Lamellar keratoplasty is often required for advanced keratoconus when contact lens wear is no longer comfortable or an ideal fit cannot be achieved. • Regional pachymetry and…
Introduction Acute corneal hydrops (ACH) is characterized by sudden-onset corneal edema, typically in the setting of a corneal ectatic disorder. It is a vision-threatening complication of keratoconus that can result…
KEY CONCEPTS • A combined procedure is justified when a single procedure cannot achieve the same safety and efficacy. • Inclusion and exclusion criteria for the individual procedures should be…
KEY CONCEPTS Mechanism: • An intrastromal corneal ring segment (ICRS) acts as a spacer, shortens arc length, and increases thickness in the cornea. • The corrective effect is correlated in…
KEY CONCEPTS • There is an inverse relationship between the diameter of the ring and its effect on the cornea. • The width of the intrastromal corneal ring segments is…
KEY CONCEPTS • Despite the increasing popularity of deep anterior lamellar keratoplasty (DALK), penetrating keratoplasty (PK) remains an important modality in the surgical management of advanced keratoconus, particularly in cases…
KEY CONCEPTS • Corneal laser surgery for keratoconus has become possible, thanks to the advent of corneal cross-linking and major improvements in customized excimer laser ablation algorithms. • Laser surgery…
