Restore Vision with Astigmatic Keratotomy
Foundations of Astigmatism
Before discussing the surgical procedure, it is important to understand what causes astigmatism and the vision challenges it creates.
Astigmatism occurs when the front surface of the eye, the cornea, is curved more in one direction than the other. Instead of being perfectly round, the cornea may resemble the shape of a football or an egg, causing light to focus unevenly on the retina.
This uneven focusing can result in issues such as glare, halos, and a general blurriness that makes everyday tasks more challenging.
Surgical Techniques and Approach
Astigmatic keratotomy works by creating precise incisions in the cornea, thereby relaxing its steep curvature and improving how light is focused on the retina. There are two primary techniques used.
Manual techniques have been used effectively for many years. A specialized diamond blade is used to make incisions along the steepest part of the cornea.
- Time-Tested Reliability
- Accessibility and Convenience
- Cost-Effectiveness
Laser-assisted astigmatic keratotomy employs a femtosecond laser, offering enhanced precision through advanced imaging. This method adjusts for small variations during surgery.
- Improved Accuracy
- Efficient Integration with other procedures
- Smoother Recovery
Preoperative Preparation and Planning
Before your surgery, our refractive eye surgeon conducts a thorough evaluation to plan your astigmatic keratotomy based on detailed measurements of your eye.
The evaluation involves several tests to assess the cornea's curvature and thickness. Key tests include:
- Manifest Refraction
- Keratometry
- Corneal Topography
- Pachymetry
Comparing Surgical Techniques
Both manual and laser-assisted techniques provide benefits and serve different needs. Surgeons choose the method that best suits your specific case.
This approach uses a diamond blade to create precise incisions near the visual axis. It is a reliable and cost-effective choice for patients with low to moderate levels of astigmatism.
Femtosecond laser-assisted keratotomy offers superior precision through advanced imaging and real-time feedback. It is especially beneficial for achieving a consistent correction.
Postoperative Care and Recovery
After the procedure, our practice provides comprehensive care to promote a smooth recovery and monitor your healing progress.
A combination of steroid and antibiotic drops is typically prescribed to reduce inflammation and prevent infection.
Many patients experience minimal discomfort and are able to resume their daily routines quickly.
Postoperative visits allow our surgeon to monitor your healing and address any residual issues to achieve the best visual outcome.
Candidate Eligibility for Astigmatic Keratotomy
Not every case of astigmatism is treated with astigmatic keratotomy. Eligibility is determined by several factors to ensure a safe and effective result.
Candidates for this procedure often have:
- A measurable degree of corneal astigmatism causing blurred or distorted vision
- An upcoming cataract surgery where addressing astigmatism can enhance overall visual outcomes
- A desire to reduce dependence on glasses or contact lenses
- Corneal thickness and overall eye health conducive to safe incisions
If you have conditions such as severe dry eye or certain corneal diseases, our surgeon may recommend exploring alternative treatment options.
Benefits and Potential Risks
Astigmatic keratotomy offers many advantages but it is important to be aware of potential risks.
The benefits of the procedure include:
- Enhanced visual clarity by correcting corneal irregularities
- Reduced dependence on corrective eyewear
- A tailored approach specific to your eye measurements and needs
- Seamless integration with cataract surgery when appropriate
Some potential risks include:
- Overcorrection or undercorrection requiring further adjustments
- Temporary discomfort during the healing process
- A small risk of infection
- The possibility of irregular astigmatism in rare cases
