Cataract Cornea
Cataract Surgery
Asan Medical Center (AMC) is equipped with state-of-the-art medical technology, including an ultrasonic emulsifier and the latest femtosecond laser-assisted cataract surgery system. This advanced technique uses femtosecond laser and low-energy ultrasound to perform precise corneal incisions and lens fragmentation, minimizing tissue damage and improving surgical safety.
The laser also enables astigmatism correction by making highly accurate arcuate incisions, helping to reduce pre-existing corneal astigmatism. As a result, patients experience clearer, sharper vision and improved visual outcomes after surgery.
In addition, AMC offers premium intraocular lens (IOL) options, including multifocal IOLs and extended depth of focus IOLs, which restore both near and distance vision, reducing or eliminating the need for near-sighted glasses.
Postoperative Care :
After cataract surgery, patients typically use eye drops containing antibiotics and anti-inflammatory agents for 4 weeks. During this time, the surgical site heals, and vision gradually improves. Around 4 to 6 weeks after the procedure, vision can be further enhanced with new eyeglasses if needed.
In cases where cataracts are accompanied by other eye diseases such as diabetic retinopathy, macular disorders, glaucoma, or optic nerve damage, visual recovery may be delayed or limited. Patients are advised to rest for at least one week postoperatively, avoiding strenuous activity and dusty environments that may cause eye injury. Watching TV, reading, and using a computer are permitted. It is also recommended to wear a protective eye shield during sleep for up to four weeks after surgery.
Corneal Transplantation
AMC provides comprehensive care for patients with corneal diseases through advanced corneal transplantation techniques tailored to the severity and type of corneal damage. The following surgical options are available
Penetrating Keratoplasty (PKP) :
A full-thickness corneal transplant in which the entire damaged cornea is replaced with a healthy donor cornea. This method is used in cases of severe corneal scarring, keratoconus, or corneal edema.
Deep Anterior Lamellar Keratoplasty (DALK) :
A partial-thickness corneal transplant that preserves the patient’s own Descemet's membrane and endothelium. It is suitable for diseases affecting only the front layers of the cornea, such as keratoconus or stromal dystrophies, and reduces the risk of graft rejection.
Descemet's Stripping Endothelial Keratoplasty (DSEK) :
A selective endothelial transplant where only the damaged endothelial layer and Descemet’s membrane are removed and replaced. It is commonly used for conditions such as Fuchs’ endothelial dystrophy and endothelial failure after intraocular surgery.
Descemet Membrane Endothelial Keratoplasty (DMEK) :
DMEK replaces only the thin Descemet’s membrane and endothelial cells. This method offers excellent visual outcomes and a low risk of rejection, and is ideal for Fuchs’ endothelial dystrophy and endothelial failure after intraocular surgery.
Each procedure is performed with meticulous care using precision instruments and microsurgical techniques. Postoperative management includes anti-inflammatory and immunosuppressive eye drops, regular follow-up visits, and vision rehabilitation. Recovery timelines and visual outcomes may vary depending on the procedure type and underlying condition.
