A 30-year-old woman was referred for a second opinion. She had chronic epitheliopathy of unknown origin in both eyes and decreased visual acuity. The patient had bilateral epithelial laser in situ keratomileusis (epi-LASIK) 3 months before the referral. A Moria epikeratome system was used in both eyes. The correction in the right eye was −5.11 +0.29 × 108 with an ablation depth of 74 μm. The correction in the left eye was −5.19 +0.50 × 53 with an ablation depth of 74 μm. According to the surgeon, the epithelial flaps were discarded in both eyes after excimer laser treatment; mitomycin-C (MMC) 0.2 mg/mL was used for 20 seconds after the treatment.

Several scenarios could have led to the unfortunate outcome in this case. Epikeratomes are designed to cut at a preselected depth to prevent stromal incorporation into the flap. However, the literature describes several cases of deep cuts that were identified after flap creation.1–3 An enhanced inflammatory response was observed in 1 case that resulted in a focal area of subepithelial haze in the region of the deep cut only. In that case, deep cuts could have resulted in removal of the epithelium as well as a significant amount of stroma. (Source: Journal of Cataract and Refractive Surgery)

Although epi-LASIK is gaining popularity, this case illustrates why the jury is still out with regard to its purported advantage. Epi-LASIK was developed to combine the advantage of PRK (no flap complications) and LASIK (faster visual recovery and less risk for haze); however, much debate remains, for example about leaving the epithelial flap on or off or performing the procedure with or without MMC.

Keratocyte differentiation to myofibroblast due to TGF-β1 produced by regenerating epithelium has been shown to be responsible for corneal haze after surface ablation procedures. Epi-LASIK, a surface ablation technique in which a flap consisting of epithelium and basement membrane is created, theoretically decreases cytokine production by maintaining a healthy epithelium. However, the epithelial flaps were discarded in this case; therefore, the procedure was converted to PRK, increasing the risk for haze. (Source: Journal of Cataract and Refractive Surgery)

We believe that knowing the preoperative and postoperative corneal thickness as well as obtaining sequential postoperative ECC and morphology assessments are essential to determine whether endothelial toxicity is playing a major role in this case. The hypothetical advantages of laser-assisted subepithelial keratectomy and epi-LASIK over PRK are the preservation of the epithelial basement membrane, or at least some components of the epithelial basement membrane, at the cleavage plane, which prevents cytokines and cell–cell interactions between epithelial cells and the underlying stromal keratocytes and bone marrow–derived stromal cells.

This is an atypical case of bilateral post epi-LASIK endotheliopathy with corneal dysfunction associated with high IOP and haze, leading to a decrease in visual acuity, photophobia, and pain. (Source: Journal of Cataract and Refractive Surgery)

We describe a technique that uses a capsular hook to obtain sutureless fibrin glue–assisted transscleral fixation of the capsular bag. The hook passes through a sclerotomy created under a scleral flap and engages the capsulorhexis rim, providing scleral fixation intraoperatively and postoperatively. A standard capsular tension ring expands the capsular fornix. The haptic of the hook is tucked into a scleral tunnel for postoperative fixation. The scleral flap is closed with fibrin glue. The glued capsular hook is used for subluxated cataracts and IOLs. (Source: Journal of Cataract and Refractive Surgery)

This article presents an overview of endophthalmitis prophylaxis and the use of intracameral antibiotics. It highlights available intracameral antibiotics with respect to pharmacology, spectrum of activity, dosage and preparation, safety, and efficacy profiles, as well as toxic anterior segment syndrome risks to better define the potential use of these medications in the prevention of endophthalmitis.

Surgical errors involving the wrong patient, wrong site (eg, wrong eye), or wrong procedure (eg, wrong intraocular lens) can have devastating consequences1,2 and are largely preventable by adherence to specific protocols.A This underscores the importance of educating ophthalmology residents in the prevention of surgical errors. However, the resident perspective on this training is not well described. We surveyed all United States ophthalmology residents to learn their perspective on current training for the prevention of surgical errors. (Source: Journal of Cataract and Refractive Surgery)

Laser in situ keratomileusis (LASIK) has an established safety profile and is an effective surgical intervention for visual defects due to myopia, hyperopia, or astigmatism.1,2 Ensuring predictable and accurate corneal flap dimensions to minimize the risk for complications (eg, buttonhole flaps, incomplete flaps, thicker-than-intended flaps) and improve patient outcome is a primary goal during LASIK.3,4 Femtosecond lasers create corneal flaps as well as or better than microkeratomes and may improve the safety of flap creation and corneal healing.

We appreciate Lau et al.1 formally describing the syndrome of acute anterior chamber shallowing and increase of intraocular pressure with no choroidal effusion. However, we believe this syndrome has been described under different names, including infusion misdirection syndrome, capsular block, intraoperative fluid misdirection, and subcapsular fluid entrapment.2,A (Source: Journal of Cataract and Refractive Surgery)

Cherfan and Melki1 reported on a corneal perforation during intrastromal astigmatic keratectomy as part of femtosecond laser–assisted cataract surgery. For new medical applications, it is fundamentally important to share experiences, particularly bad ones, within the medical community. It is a testament to the authors' surgical skills and experience that this challenge was met in the most appropriate way and the patient emerged with 20/20 visual acuity in the eye.
