Randomized Controlled Trial
Comparison of a Supraglottic Gel Device and an Endotracheal Tube in Keratoplasty Performed Under General Anesthesia: A Randomized Clinical Trial.
To assess the safety of a laryngeal mask (i-gel) in keratoplasty performed under general anesthesia. ⋯ The use of i-gel for keratoplasty under general anesthesia appears to be safe, reduces the risk of potential ocular hypertension during recovery, and saves recovery time.

Comparative Study
Utility of Assessing Nerve Morphology in Central Cornea Versus Whorl Area for Diagnosing Diabetic Peripheral Neuropathy.
To compare small nerve fiber damage in the central cornea and whorl area in participants with diabetic peripheral neuropathy (DPN) and to examine the accuracy of evaluating these 2 anatomical sites for the diagnosis of DPN. ⋯ Small nerve fiber pathology is comparable at the central and whorl anatomical sites of the cornea. Quantification of CNFL from the corneal center is as accurate as CNFL quantification of the whorl area for the diagnosis of DPN.

To report intraoperative and 1-year postoperative results of the pachy-bubble technique for deep anterior lamellar keratoplasty (DALK). ⋯ Bubble formation, especially type 1, is the key to decrease the risk of perforation in DALK. The pachy-bubble was safe, effective, and reproducible in promoting DALK with air bubble and viscobubble formation with a short learning curve.

Observational Study
Evaluating the need for close follow-up after removal of a noncomplicated corneal foreign body.
The purpose of this study was to evaluate the need for close follow-up after removal of noncomplicated corneal foreign bodies. ⋯ Few noncomplicated injuries develop infectious keratitis. We recommend fewer follow-ups for these injuries. However, if patients develop any worsening in eye pain, irritation, redness, or decrease in their visual acuity, they should return promptly for reassessment.

Case Reports
Herpes zoster stromal keratitis after varicella vaccine booster in a pediatric patient.
In this study, the case of a healthy pediatric patient who presented with herpes zoster (HZ) stromal keratitis after vaccination with live attenuated varicella vaccine (Varivax) and subsequent booster is described. ⋯ HZ ophthalmicus with stromal keratitis is a rare but potentially damaging manifestation of the varicella zoster virus in the pediatric population. Long-term data regarding reactivation rates in the post-vaccination era are still limited. Close follow-up is needed to ensure resolution of the infiltrates, and reactivation may require long-term steroid therapy.
