The aqueous humor is a high-yield liquid biopsy for retinoblastoma, intraocular cancer that cannot be biopsied in vivo due to the risk of extraocular spread. Herein, a method for safely extracting aqueous humor via clear corneal paracentesis and steps for genomic analysis to identify prognostic biomarkers are presented.

2012
Endothelial corneal transplantation is a surgical technique for treatment of posterior corneal diseases. Mechanical microkeratome dissection to prepare tissue results in thinner, more symmetric grafts with less endothelial cell loss and improved outcomes. Dissections can be performed at the eye bank prior to corneal transplantation surgery.

Corneal collagen cross-linking (CXL) is the only conservative treatment currently available to halt keratoconus progression by improving the biomechanical rigidity of the corneal stroma. The aim of this manuscript is to highlight the methods of three different protocols of CXL: conventional CXL (C-CXL), accelerated CXL (A-CXL), and iontophoresis CXL (I-CXL).

Current in vitro models for evaluating contact lenses (CLs) and other eye-related applications are severely limited. The presented ocular platform simulates physiological tear flow, tear volume, air exposure and mechanical wear. This system is highly versatile and can be applied to various in vitro analyses with CLs.

Neovascularization (NV) of the cornea can complicate multiple visual pathologies. Utilizing a controlled, alkali-burn injury model, a quantifiable level of corneal NV can be produced for mechanistic study of corneal NV and evaluation of potential therapies for neovascular disorders.
FAQs
The cornea contains sensory nerves that respond when its surface is disturbed by an eyelash. Their activation produces protective reflexes, especially blinking and increased tearing, which may help clear the irritant from the eye. Redness and discomfort can accompany these responses, reflecting ocular surface irritation rather than necessarily indicating a persistent injury.
Rubbing adds mechanical friction to an already irritated corneal surface. If an eyelash remains trapped or continues touching the eye, that repeated mechanical stress can damage the corneal epithelium, the surface layer of the cornea, and contribute to an abrasion. Limiting continued irritation is therefore important when discomfort persists after contact.
Transient contact may resolve after the eyelash moves away or is appropriately removed. Trichiasis is different because eyelashes are misdirected and repeatedly touch the eye, creating an ongoing source of irritation. This distinction matters clinically: recurrent symptoms suggest a continuing eyelash-position problem rather than a single brief episode of corneal contact.
Assessment determines whether the contact is transient, whether an eyelash is trapped against the eye, and whether the corneal surface has been injured. Clinicians also consider findings such as persistent redness, discomfort, or visual symptoms and distinguish a single episode from repeated contact associated with misdirected lashes. These observations guide appropriate removal and follow-up.
Careful examination followed by appropriate removal eliminates the immediate mechanical source of irritation when an eyelash remains against the cornea. This can relieve the foreign-body sensation and reduce continued stimulation of corneal sensory nerves. Removing the source also helps limit ongoing epithelial stress, although persistent symptoms may indicate that professional evaluation is still needed.
Professional evaluation is warranted when pain, blurred vision, light sensitivity, or redness persists. These findings may indicate more than brief surface irritation, including a corneal abrasion or continuing contact from a misdirected eyelash. Medical assessment can identify the cause, examine the corneal surface, and determine whether careful removal or further management is appropriate.
