Ablation

Ablation is a medical term referring to the precise removal of tissue. In eye surgery, particularly laser vision correction, ablation is used to reshape the cornea to correct refractive errors like myopia, hyperopia, and astigmatism. The process typically involves using a laser to remove microscopic amounts of corneal tissue, allowing light to properly focus on the retina for clearer vision. This technique is central to modern corrective eye surgeries such as LASIK and PRK.

In LASIK surgery, ablation is performed using an excimer laser to reshape the cornea. After creating a thin flap in the cornea, the laser targets specific areas, vaporizing corneal tissue with extreme precision. This reshaping corrects the eye’s focusing power, improving vision. The laser is guided by detailed measurements of the eye, ensuring accuracy and safety. Ablation in LASIK is painless and completed in seconds, making it a quick and effective vision correction method.

• Laser Ablation: Uses focused light energy to destroy targeted tissue precisely with minimal damage to surrounding areas.

• Cryoablation: Destroys tissue by freezing it, causing cells to die; commonly used for tumors and heart arrhythmias.

• Radiofrequency Ablation (RFA): Uses heat generated by radio waves to cauterize or destroy abnormal tissue, effective for pain relief and tumor treatment.

• Each type varies in technique, benefits, and applications depending on medical needs.

Ablation is primarily used in refractive eye surgeries to correct vision by reshaping the cornea. It also has applications in treating glaucoma by reducing intraocular pressure and in retinal procedures to seal retinal tears or detachments. By selectively removing or destroying targeted tissue, ablation helps restore or preserve vision, making it a crucial technique in modern ophthalmology.

• Patient is prepped and given local anesthesia or sedation.

• A thin catheter is inserted through a blood vessel, usually in the groin.

• Using imaging guidance, the catheter is navigated to the target area in the heart.

• Radiofrequency energy or cryotherapy is applied to destroy abnormal tissue causing arrhythmia.

• The catheter is removed, and pressure is applied to prevent bleeding.

• Patient is monitored before discharge, with follow-up planned to assess success.

• Precise removal of damaged or diseased eye tissue

• Minimally invasive procedure with faster recovery time

• Reduces risk of infection compared to traditional surgery

• Improves vision clarity by reshaping corneal tissue

• Helps treat conditions like glaucoma, cataracts, and retinal disorders

• Minimizes discomfort and scarring

• Enhances overall surgical outcomes and patient satisfaction

• Often performed using advanced laser technology for accuracy

• Common risks include bleeding, infection, and damage to surrounding tissues.

• Rare complications may involve blood clots or heart rhythm problems.

• Mild pain or discomfort at the procedure site is typical.

• Recovery usually takes a few days to a week, with rest advised.

• Avoid strenuous activities initially; follow your doctor’s guidelines.

• Regular follow-up checks are important to monitor heart function and ensure successful results.

• Contact your healthcare provider if you experience severe pain, swelling, or unusual symptoms.
