Refractive surgery after corneal transplantation

Current Opinion in Ophthalmology, 2005
Many patients who have undergone corneal transplantation are unable to achieve satisfactory visual acuity with spectacle and contact lens correction alone. For these patients, refractive surgery becomes a viable option to reduce the post-keratoplasty ametropia. With the many recent advances in refractive surgery for naturally occurring refractive error,

Refractive surgery after corneal transplant

Current Opinion in Ophthalmology, 2010
Ametropia and astigmatism following successful penetrating keratoplasty can seriously impact a patient's quality of vision. Similar limitations can result following anterior lamellar keratoplasty (ALK) and Descemet's stripping endothelial keratoplasty (DSEK).

Refractive Corneal Surgery

2019
In patients undergoing corneal surgery, topography is useful in preoperative planning, intraoperative modification and postoperative monitoring and problem-solving. Myopia is addressed by corneal flattening, hyperopia by corneal steepening and regular astigmatism by differentially addressing perpendicular meridian.

Corneal endothelium after refractive surgery

Journal of Cataract and Refractive Surgery, 2011
The endothelium is vital to the health and optical clarity of the human cornea. The safety of procedures to correct refractive errors depends on preservation of an intact corneal endothelium. Disease states and genetic and environmental factors affect the corneal endothelium; an unstable corneal endothelium can impact the success of refractive surgery.

Refractive Corneal Surgery

2013
Incisional techniques for reducing corneal astigmatism are based on Gauss’ law of inelastic domes. A circumferential arcuate incision made on the steep corneal axis will cause slight flattening of that axis coupled with a corresponding steepening of the orthogonal axis.
