Summary
Rapidly progressing corneal epithelial in-growth (EI) after LASIK enhancement surgery can significantly decrease visual acuity (VA) within days. Early diagnosis using optical coherence tomography (OCT) and corneal topography is crucial for prompt treatment and vision recovery.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Refractive Surgery
Background:
- Laser-Assisted In Situ Keratomileusis (LASIK) is a common refractive surgery.
- Enhancement LASIK procedures are performed to correct residual refractive errors.
- Corneal epithelial in-growth (EI) is a rare but potentially vision-threatening complication following LASIK.
Observation:
- A 37-year-old male experienced rapid visual acuity deterioration post-LASIK enhancement surgery.
- Visual acuity decreased significantly within the first postoperative day and continued to decline.
- Distinctive features were observed on corneal topography and optical coherence tomography (OCT).
Findings:
- The patient was diagnosed with corneal epithelial in-growth (EI) postoperatively.
- Ectopic corneal epithelial cells were identified, leading to reduced visual acuity (VA).
- Prompt treatment involving scraping of ectopic cells resulted in corneal transparency and improved VA.
Implications:
- Early postoperative EI can occur rapidly, even within one day after enhancement surgery.
- OCT and corneal topography are valuable diagnostic tools for identifying corneal EI.
- Timely diagnosis and intervention are essential for managing corneal EI and preserving visual function.

01:16Focusing of Light in the Eye
2.8K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

6.0K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

01:25Glaucoma: Overview
570
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
