Summary
This summary is machine-generated.This study presents a novel three-phase surgical technique to restore vision in patients with high myopia and prior epikeratophakia surgery. The approach successfully improved visual acuity by addressing corneal irregularities and lens opacities.
Area Of Science
- Ophthalmology
- Corneal Surgery
- Refractive Surgery
Background
- Progressive visual decline can occur in patients with myopia magna and a history of epikeratophakia.
- Management of such cases presents unique challenges due to prior corneal surgery.
Purpose Of The Study
- To describe a novel three-phase surgical strategy for managing visual deterioration in a patient with myopia magna and prior epikeratophakia.
- To evaluate the efficacy of this approach in improving visual acuity and corneal regularity.
Main Methods
- A three-phase surgical approach was employed: epikeratophakia lenticule removal, cataract extraction with intraocular lens implantation, and transepithelial topography-guided photorefractive keratectomy (trans-PRK).
- Preoperative and postoperative data including refraction, corneal topography, and visual acuity were meticulously analyzed.
Main Results
- The right eye, treated with the full three-phase approach, showed significant corneal surface regularization and improved visual acuity to 0.15 logMAR.
- The left eye, managed with a modified two-phase approach without lenticule removal, also demonstrated enhanced visual outcomes.
Conclusions
- A three-phase surgical strategy, incorporating lenticule removal, cataract surgery, and topography-guided PRK, offers a viable option for visual rehabilitation in phakic patients post-epikeratophakia.
- This approach may be beneficial for managing complex visual decline in eyes with a history of epikeratophakia.

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...
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...
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...
