Cornea
-
To determine changes in corneal thickness after topical anesthesia. ⋯ Some individuals can present important increases and decreases in corneal thickness values after anesthetic eye drops. This effect of anesthetic eye drops must be considered by refractive surgeons when carrying out preoperative laser in situ keratomileusis corneal thickness measurements.
-
To report a case of fragile cornea associated with osteogenesis imperfecta type I in which primary penetrating keratoplasty was done as a tectonic procedure. ⋯ Primary penetrating keratoplasty is a viable option to restore ocular integrity in fragile corneas following trauma when tissue loss precludes simple repair.
-
To study the efficacy and safety of using cryopreserved human amniotic membrane (AM) graft as a patch graft to reduce stromal melting and promote reepithelialization in extensive infectious scleral and corneoscleral ulcers. ⋯ The AM graft is effective in promoting conjunctival reepithelialization and reducing scleral melting and inflammation and can be considered as an alternative biomaterial to improve wound healing in scleral and corneoscleral ulcerations.
-
To describe a case of full-thickness corneal laceration and intraocular foreign body in an eye that underwent laser-assisted in situ keratomileusis (LASIK). ⋯ Penetrating trauma of the cornea did not lead to flap-related complications in this post-LASIK eye. Repair of the corneal laceration and removal of the intraocular foreign body after LASIK were managed without complications. Care must be taken to try not to manipulate or lift the LASIK flap during corneal laceration repair.

Case Reports
Progressive ulcerative keratitis related to the use of topical chlorhexidine gluconate (0.02%).
To report a case of progressive ulcerative keratitis related to the use of topical chlorhexidine gluconate 0.02%. ⋯ We think that the topical use of chlorhexidine gluconate 0.02% may have resulted in a progressive ulcerative keratitis in our patient.
