What are the Different Laser Systems for Eye Surgery?

Laser systems include the Excimer Laser, widely known for its role in LASIK and PRK procedures to reshape the cornea for correcting refractive errors. The Femtosecond Laser, known for its ultra-short pulses, provides bladeless flap creation in LASIK and precise cuts in corneal and lens surgeries.

There are other types of laser systems, and we’ll discuss more on that. And keep in mind that, each laser type is designed for specific applications, ensuring precision and minimizing recovery times.

Excimer Laser (LASIK, PRK)

The Excimer Laser is instrumental in reshaping the cornea to correct refractive errors such as myopia, hyperopia, and astigmatism. This laser works by precisely removing corneal tissue, improving the eye's focusing power. Maintenance includes regular calibration to ensure accuracy and effectiveness, which is vital for achieving optimal vision correction outcomes.

Femtosecond Laser

The Femtosecond Laser is celebrated for its precision and versatility. Used in LASIK for creating corneal flaps and in cataract surgery for lens fragmentation, this laser offers a bladeless approach, reducing risks and improving recovery times. Regular system updates and maintenance are crucial for operational efficiency and safety.

YAG Laser

The YAG Laser is primarily used for posterior capsulotomy after cataract surgery and for peripheral iridotomy in glaucoma treatment. It works by creating a small opening in the capsule or iris to improve fluid flow within the eye. Maintaining this laser involves periodic checks and adjustments to ensure it delivers the correct energy levels for safe and effective treatment.

Argon Laser

The Argon Laser is a fundamental tool in retinal treatments, utilizing blue-green wavelengths to perform photocoagulation. This process is crucial for treating diabetic retinopathy and other retinal disorders by sealing off bleeding vessels and repairing retinal tears. Maintenance of the Argon Laser includes regular checks of its energy output and alignment to ensure effective and safe operation.

Diode Laser

Diode Lasers offer versatility with their use in both cyclophotocoagulation for glaucoma and certain retinal treatments. They work by delivering laser energy to target tissues, reducing intraocular pressure or sealing retinal tears. Proper maintenance involves routine inspection of the laser emitter and optical components, ensuring they are free of debris and correctly aligned.

SLT Laser (Selective Laser Trabeculoplasty)

The SLT Laser is specifically designed for glaucoma treatment, targeting the trabecular meshwork to enhance fluid drainage from the eye. This non-invasive procedure is an important option for patients needing intraocular pressure management. Regular maintenance includes checking the laser’s calibration and cleaning the delivery system to prevent any blockage that could affect the laser's function.
