    Management of Corneal Haze After Photorefractive Keratectomy

    Photorefractive keratectomy (PRK) is a safe and popular corneal surgery performed worldwide. Nevertheless, there is potential risk of corneal haze development after surgery. Proper management of post PRK haze is important for good visual outcome.

    Preservative-Free Topical Anesthetic Unit-Dose Eye Drops for the Management of Postoperative Pain Following Photorefractive Keratectomy

    Photorefractive keratectomy (PRK) is a well-established surface ablation procedure for correction of refractive errors which involves the removal of corneal epithelium in a large diameter usually more than 6 mm, followed by stromal ablation [ 1 ].

    Assessment of the specificity of corvis biomechanical index-laser vision correction (CBI-LVC) in stable corneas after phototherapeutic keratectomy

    Post-Laser Vision Correction (LVC) ectasia is part of a wider group of pathologies named as “ectatic ocular disorders”, in which the cornea progressively undergoes a process of thinning and steepening. Corneal ectasia strongly impacts vision and …

    Diffuse lamellar keratitis as a rare complication of diamond burr superficial keratectomy for recurrent corneal erosion: a case report

    Laser in situ keratomileusis (LASIK) is one of the most common corneal refractive surgeries to correct refractive error [ 1 ]. Despite well-established safety and efficacy, several postoperative complications may occur even after successful surgery …

    Role of corneal epithelial thickness during myopic regression in femtosecond laser-assisted in situ keratomileusis and transepithelial photorefractive keratectomy

    Uncorrected myopia is one of the main causes of visual impairment worldwide. Since the 1990s, corneal refractive surgery has become a safe and effective method for correcting myopia, which has a long-term and stable outcome. However, refractive …

    Goldmann and modified Goldmann tonometry measuring intraocular pressure changes in eyes which underwent myopic laser in situ Keratomileusis and photorefractive keratectomy

    A corneal biomechanical correcting Goldmann prism measures significantly less IOP reduction following LASIK and PRK compared to a standard Goldmann prism. The IOP reduction tends to be correlated to procedural thinning of the cornea.

    Clinical outcomes of single-step transepithelial photorefractive keratectomy and off-flap epipolis-laser in situ keratomileusis in moderate to high myopia: 12-month follow-up

    Photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) were introduced decades ago [ 1 , 2 ], and with recent advances in surgical techniques and adjunctive mitomycin-C medication, the outcome of modern surface ablation is …

    Symmetric offset versus asymmetric offset ablation with transepithelial refractive keratectomy

    There is an ever-growing body of evidence that using the pupil-vertex offset (i.e. centring refractive correction on the corneal vertex) produces better outcomes. Thus, “offset”, i.e. “corneal vertex” centred refractive corrections, are an …

    Factors associated with changes in posterior corneal surface following photorefractive keratectomy

    Laser refractive surgery is the most common surgical technique for correcting refractive errors. There has been an increase in laser assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) surgery in recent years [ 1 ]. Each …

    Effects of the pharmaceutical formulation of topical medications on corneal epithelial healing after phototherapeutic keratectomy

    The use of generic drugs has been recommended in Japan [ 1 , 2 ], but the pharmaceutical formulation of topical ocular medications can be different from brand-name drugs according to different additives and preservatives [ 3 ]. However, differences …

    Transepithelial photorefractive keratectomy to treat mild myopia

    Photorefractive keratectomy (PRK) employs an excimer laser ablation of the anterior corneal stroma beneath the epithelium [ 1 , 2 ]. Traditionally, the corneal epithelium is manually scraped before ablation. Several techniques have been developed …
