What Does Having a Misshapen Cornea Mean?

If you rely on glasses or contact lenses in order to see objects either far away or up close, then you are described as having a refractive error.

 

A refractive error occurs when light that enters the eye falls in front of or behind the retina rather than on it creating blurred vision.

 

Most of the eye’s refractive power is located in the cornea, which is a transparent, dome-shaped layer located towards the front of the eye.

 

In a normal eye with perfect 20/20 vision, the cornea is a perfect spherical shape, but a refractive error indicates a misshapen cornea.

What type of refractive error do I have?

Myopia: In myopic eyes either the eye itself is too long or else the cornea is too steep which cause rays of light to fall short when they reach the back of your eye. Objects up close are perfectly clear but anything in the distance appears blurred, hence the term shortsightedness.

 

Hyperopia: In the case of hyperopic eyes or long-sightedness, the eye can be too short or else the cornea is too flat which contribute to light being focused beyond the retina. With hyperopia, far away objects are not an issue, but you have difficulty making out near objects.

 

Astigmatism: If your cornea isn’t spherical and is instead oval, then you have astigmatism, which usually manifests during childhood. Light cannot bend correctly and contribute to blurred vision. Sometimes astigmatism presents itself along with either myopia or hyperopia.

How does Laser Eye Surgery reshape my cornea?

Laser Eye Surgery removes microscopic amounts of corneal tissue to either reduce or increase the gradient of you cornea so that light bend correctly and focus clear images onto the retina.

 

Because the exact amount of excess corneal tissue is removed, vision is immediately corrected and you can resume to your normal routine, usually after 24hours.

I had a great experience and Optilase getting laser eye surgery, it was without a doubt the best money I ever spent and wish I did it years ago! I rave about it to anyone who'll listen. From my initial consultation to the surgery itself in Dublin and the aftercare in Galway I couldn't rate it highly enough. The staff were so professional, informative, friendly and attentative throughout the whole process. Extremely happy customer!

Had such an amazing experience with Optilase in Cork. Such a brilliant team, they all made me feel so relaxed and explained everything so well. They reassured me so much on the day of my surgery, and I never felt rushed with any questions. I would highly recommend Optilase to anyone even considering laser eye surgery. I am the most nervous and skeptical person and it’s truly the best thing I ever did, there is honestly nothing to be worried about!! I had zero pain whatsoever and my vision was clear by that evening and 100% perfect the next morning, it’s truly amazing! Wish I got it done years ago. I have so much freedom now without contact lenses or glasses, it’s so hard to believe my vision is fixed!!

My glasses has always made me feel self conscious to the point of not wearing them. I had my free consultation for eligibility with Rachel who was helpful and really put me at ease about the entire procedure. Elizabeth in reception was friendly and welcoming throughout each visit helping me set up all my upcoming appointments and fit me in for my surgery to meet my schedule. The day of surgery I was brought upstairs for re-scans. Paul did these and he was extremely kind. He answered all my questions making me feel at ease. After I was then called by Fiona who was assisting Dr. Tom in my surgery. I met Dr. Tom who ran over the procedure and answered questions I had. Fiona then went through the things to be mindful of after surgery showing me the three different eye drops to be taken and then helped me prep for surgery. The surgery itself was so quick. I first laid down on the chair and they dosed my eyes in eye drops which were to stop infections and aesthetic to keep my eyes open. Dr. Tom and the team began. It was such a quick painless procedure I couldn’t believe it was finished so quick. Already getting up I felt I could see better although a little fuzzy. Fiona guided me to the dark area of the reception while I waited to go home. The girls in reception had already called my dad and he was on the way. Sitting there I could already read the signs on the wall (I couldn’t when I had come in). Paul and Fiona came and sat with me for a second in reception asking me how I was and how I got on which was so nice of them. My dad collected me and I put my sunglasses on. It was a sunny day and I’m going to be honest the car ride home for me was the hardest part. Fiona told me my eyes would become heavy when the eye drops wore off. I felt the light from the sun in the car ride home was harsh on my eyes and my eyes stung. This was instantly relieved when I got home and went to my room which was in complete darkness. The first two hours my eyes were a little sore and stingy. Then this all faded very quick. No stinging. No pain. Nothing. All great. My eyes improving more and more as the day went on. I was nervous about the eye drops but set them up on my table with an alarm and it’s so easy to just pop them in. My eyes were quite red with two red dots on each side. I rested up for the evening and I wore my dark glasses they provided for a lot of the evening to really rest my eyes and by that night my vision was very sharp it was amazing. I slept very well with my eye mask and not once did I have to take painkillers. My follow up appointment was with Michaela who was lovely and stated I have 20/20 vision and my eyes look good. She also said the redness is 100% normal and is just bruising of the eye from the suction. My experience has been amazing. I honestly can’t thank the staff enough. Each and every one of them were so nice and welcoming and the liking to answer all my questions. If you have any doubts at all; I wouldn’t. Get it done if you can. I wish I got it done sooner. Any questions or using a refer a friend find me on fb or instagram with the name above 😊

I recently had my LASIK eye surgery done at Optilase and I couldn’t be happier with the entire experience. From the moment I walked in, the team made me feel completely at ease. A special mention goes to Optometrist Dan, who was incredibly professional, patient, and reassuring throughout the whole process. Dan explained every step clearly, answered all my questions, and made sure I felt confident before and after the procedure. The surgery itself was quick and comfortable, and my vision improvement has been amazing. I highly recommend Optilase and especially Dan for anyone considering LASIK. Excellent service, fantastic results, and a team you can truly trust.
