Glasses are only appropriate in cases of anisometropy lower than 3.0 D or astigmatism lower than 4.0 D. The glasses are only appropriate in cases of anisometropy lower than 3.0 D or astigmatism lower than 4.0 D. Most patients who cannot be rehabilitated with glasses can achieve adequate vision correction with contact lenses, which should be considered a first-line treatment for visual correction in patients after keratoplasty. Contact lenses are successful in 80-90% of cases.
Although rare, HSK reactivation can occur after corneal refraction procedures. This is important as recurrence leads to worse visual outcomes. However, surgery should not be excluded for all patients with previous ocular HSV. Patients with previous HSK who have been free of the disease for at least one year, have no signs of active infection and are being treated prophylactically may be considered for corneal refractive surgery.
As with any operation, each patient should be counseled about the risks and benefits of the procedure. However, there is a lack of literature on HSK prophylaxis before and after surgery. With more animal studies and randomized control trials, ophthalmologists will be able to better advise their patients on operations that could significantly improve visual acuity. Once vision has stabilized, which occurs approximately three months after the operation, patients are prescribed new glasses.
In some cases, contact lenses must be worn on the treated eyespot to achieve better corrected vision. Eight months after the corneal transplant procedure in our office, the doctor will decide whether to remove the ongoing suture. This depends on how you healed and the degree of residual eye damage. While systemic comorbidities, such as malignancies and cardiovascular diseases, disqualify affected people from donating other organs and tissues, these conditions do not necessarily prevent people from donating their corneas.
Common eye conditions, such as cataracts, glaucoma, and a history of LASIK surgery, also do not prevent donation. It is important to note that no pairing process is required between the donor and the recipient. In patients undergoing penetrating keratoplasty (PK) for Fuchs endothelial corneal dystrophy or pseudophachic corneal edema, the incompatibility of the ABO blood group, the Rh factor and the combined antigen did not increase the risk of transplant failure attributable to graft rejection or to differences in endothelial cell survival 5 years after surgery (. The expression of ABO antigens is not uniform in all layers of the cornea.
In addition, compatibility with human leukocyte antigens, as studied in the Collaborative Corneal Transplant Study, provided no benefit in relation to corneal transplant rejection (. The incidence of herpes simplex keratitis (HSK) in patients who undergo refractive corneal surgery is higher than in the general population, and several reports of cases of ocular morbidity due to HSK infection after refractive corneal surgery have been published. This review summarizes the current literature on HSK reactivation after refractive corneal surgery and provides a guide for considering refractive corneal surgery in a patient with a history of HSK.
