Corneal infiltrates after excimer laser photorefractive keratectomy and LASIK

Bilateral methicillin-resistant Staphylococcus aureus keratitis after photorefractive keratectomy

“…The reported risk for keratitis is between 0.01% and 0.8% 5,8,9 after PRK and between 0.01% and 0.1% after LASIK. 5,10,11 The potentially increased risk after PRK is likely associated with the inherent creation of a large epithelial defect and the therapeutic use of a contact lens in the early postoperative period.…”

“…5,10,11 The potentially increased risk after PRK is likely associated with the inherent creation of a large epithelial defect and the therapeutic use of a contact lens in the early postoperative period. 6,7,[12][13][14][15] Most postoperative infections are caused by gram-positive organisms including S aureus, coagulase-negative Staphylococcus species, and Streptococcus species.…”

“…3,4 However, the risk for infectious keratitis may be greater after surface ablation. 5 Four cases of methicillin-resistant Staphylococcus aureus (MRSA) bacterial keratitis after PRK have been reported. [6][7][8] We report a case of bilateral methicillinresistant, fluoroquinolone-resistant S aureus keratitis after PRK in a patient with a history of chronic systemic fluoroquinolone use.…”

Fluoroquinolone therapy in a rabbit model of post-LASIK methicillin-resistant Staphylococcus aureus keratitis

“…1 To prevent infections associated with LASIK, such as keratitis, ophthalmologists administer an antibiotic as a prophylactic agent that is effective against the most common causes, Staphylococcus and Mycobacterium. 1,2,6,7 If post-LASIK staphylococcal keratitis does occur, treatment involves the topical application of antibiotic agents, often in conjunction with lifting the corneal flap and scraping underneath for culture and irrigation of the corneal flap-stromal interface. Established antibiotics for ocular prophylaxis and treatment of Staphylococcus keratitis include fourthgeneration fluoroquinolones such as moxifloxacin or gatifloxacin.…”

Toric Intraocular Lenses in Cataract Surgery

“…However, corneal incision procedures are relatively unpredictable and laser refractive surgery may be associated with complications such as dry eyes, wound healing problems and infections. (Bayramlar, Daglioglu et al 2003;de Oliveira, Solari et al 2006;Kato, Toda et al 2008;Thomas, Brunstetter et al 2008) Toric IOLs now provide the opportunity to correct corneal astigmatism, offering patients with pre-existing astigmatism optimal distance vision without the use of spectacles or contact lenses with a cylindrical correction. Furthermore, the recent introduction of multifocal toric IOLs offers patient with pre-existent corneal astigmatism the opportunity not only to achieve spectacle independence for distance vision, but also for near and intermediate visual acuities.…”
