Summary
Femtosecond laser LASIK flaps remained stable after severe eye trauma. The flap did not complicate surgical repair or affect visual acuity outcomes.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Laser Vision Correction
Background:
- Laser-assisted in situ keratomileusis (LASIK) is a common refractive surgery.
- Femtosecond lasers are used for corneal flap creation in LASIK.
- Ocular trauma can compromise corneal integrity.
Observation:
- Two patients with prior uneventful femtosecond LASIK experienced severe open globe injuries.
- Primary surgical repair of the globe injuries was performed.
- LASIK flap stability was assessed during surgical repair and via histopathology.
Findings:
- No LASIK flap dislocation was observed in either patient during globe repair.
- Histopathological examination confirmed an intact LASIK flap in one case.
- The femtosecond LASIK flap remained stable despite severe corneal trauma.
Implications:
- Femtosecond LASIK flaps demonstrate significant stability even after major ocular trauma.
- The presence of a femtosecond LASIK flap did not complicate the management of severe eye injuries.
- LASIK flap integrity did not negatively impact best-corrected visual acuity (BCVA) post-trauma.

01:28Angle Closure Glaucoma: Treatment
1.0K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:25Glaucoma: Overview
1.1K
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...

01:27Open Angle Glaucoma: Treatment
900
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
