How can corneal astigmatism be corrected?

Dear ophthalmologist,
My name is Leon Kleine and I have been experiencing eye problems for quite some time now. During my last visit to the optician, it was determined that I have astigmatism. This may explain my increasing vision problems such as blurry vision, double vision, and headaches. I am concerned that my vision impairment could worsen further and I wonder if there are any ways to correct this astigmatism.
I currently wear glasses, but they no longer seem to be effective. Therefore, I am interested in alternative methods such as contact lenses or even surgery to improve my vision. However, I have concerns about which type of correction would be best for me and what risks may be associated with it.
Could you please explain to me in more detail the options for correcting astigmatism and the pros and cons of each? Are there specific tests that need to be done before undergoing correction? And what is the typical success rate of such procedures?
I would greatly appreciate your assistance in this matter, as my eyesight is very important to me and I would like to be well informed about all my options to make the best decision for my health.
Thank you in advance for your support.
Sincerely,
Leon Kleine
Dear Mr. Kleine,
Thank you for your detailed inquiry regarding your astigmatism and the associated vision problems. It is understandable that you are concerned about your eyesight and are looking for ways to improve it. I will be happy to provide you with all the information about the various options for correcting astigmatism.
Astigmatism, a condition in which the cornea is not perfectly round but has an irregular curvature, can cause distorted and blurry vision both near and far, double vision, and headaches, as you have already described. To correct astigmatism, there are several options:
1. Glasses: Glasses with special cylindrical lenses can correct astigmatism. However, it may be that glasses are no longer sufficient if your vision continues to deteriorate.
2. Contact lenses: Special toric contact lenses are another option for correcting astigmatism. These lenses have different curvatures to compensate for the irregular corneal shape. Contact lenses are a good alternative to glasses but may not be suitable for everyone.
3. Corneal surgery: In cases of more significant astigmatism, a surgery such as laser treatment (LASIK, PRK) may be considered. In this procedure, the cornea is selectively reshaped to achieve a uniform curvature. Such surgery can permanently improve vision, but also carries risks such as infections or night vision issues.
Before correcting astigmatism, it is important to undergo a thorough eye examination. This will include an assessment of the exact shape of the cornea, visual acuity, and any accompanying eye conditions in order to choose the best method for correction.
The success of such procedures depends on various factors such as the extent of astigmatism, corneal thickness, patient age, and any accompanying conditions. Generally, the success rate of corneal surgeries is high, and most patients report significantly improved vision after the procedure.
It is important that you seek advice from an experienced eye doctor to find the most suitable method for correcting your astigmatism. I recommend scheduling an appointment in my online consultation to discuss your individual situation and address any remaining questions.
I hope this information is helpful to you and I am available to answer any further questions you may have.
Best regards,
Ammelie Niemeyer, Ophthalmologist
