Orthokeratology

What is Orthokeratology?

Orthokeratology (often called Ortho-K) is a non-surgical process which flattens the front part of the eye (the cornea) using contact lenses. Ortho-K uses specially designed, tailor-made rigid gas permeable contact lenses that are worn at night. The lenses flatten the cornea to reduce myopia so that when the lenses are removed in the morning, vision is seamlessly corrected. The effect provides great vision without lenses all day.

 

How long has it been available?

The procedure was first used over 40 years ago. 

Why has it become popular now?

Advances in computer-controlled manufacturing methods and new high-tech lens materials have made accurate and controlled Ortho-k lenses a possibility. 

 

Is it risky? 

As with all contact lenses, there is always a small risk associated with lens wear, so it is important to follow the advice we give in respect of lens hygiene, cleaning and procedures.

 

What is involved? 

We take a special photograph of each eye in order to digitally design your lenses based on the shape of each eye and your optical prescription. 

When the lenses arrive, we will check that they fit properly and teach you how to use the lenses. We'll need to see you for a follow-up appointment after your first night of wear to check that the lenses are working as intended. Assuming that there are no problems, you will be asked to wear the lens for up to seven nights before another contact lens check.  Once you are comfortable with your ortho-k lenses, we will need to review your lenses and check the health of your eyes every six or twelve months.

 

How long does it take to work?

Many people see really well after one night of wear, but in some cases it may take up to two weeks before to reach the full effect.

 

Do I have to wear my lenses every night?

Most people use the lenses every night but some people use the lenses every other night without a problem. 

 

Do I need regular check ups?

Absolutely. It is very important to regularly check the health of the eye while wearing Ortho-K lenses.

Are the lenses comfortable?

The lenses are specifically designed to be worn when you are asleep. For this reason, when the eyes are closed, there is very little sensation and most people find that they can wear the lenses without any problem.

Can I see with the lenses in?

Yes. Vision is usually excellent when you are wearing the lenses.

Is everyone suitable?

Unfortunately not. It works with short sighted people who have moderate amounts of astigmatism.
