Ortho-K Vision Correction

Ortho-K is the short name for Orthokeratology (Corneal Reshaping), an amazing breakthrough in corrective vision which allows excellent daytime vision without glasses or contact lenses.

Near Perfect Day Time Vision Without Contacts or Glasses Orthokeratology is a non-surgical, 100% naturally reversible gentle reshaping of the eye using specially designed contact lenses that you wear whilst sleeping. After waking in the morning, you remove your Ortho K contact lenses to find near perfect vision. Your reshaped corneal surface allows clear and natural vision for the rest of your waking day… without the need for prescription glasses or contact lenses!

Applies to most Optical Conditions Wearing Ortho K contact lenses overnight will give you between 1-2 days of near perfect vision, depending on the degree of optical correction you require. It works best with short sightedness, but can also correct farsightedness, presbyopia (the need for reading glasses) and astigmatism.

Safe, Non-surgical, Naturally Reversible  The effect is not permanent, and your eyes will return to normal after a few days if you stop wearing the Ortho K contact lenses overnight. It’s pleasing to know there are no greater risks in wearing Ortho K lenses than with normal contacts. The Ortho K lenses are surprisingly comfortable to wear and most people comment that they forget they have lenses in the eyes after the first night of sleeping with them in.


How does it work?

The lenses are worn every night for about 6-8 hours. During your sleep, the rigid, gas permeable contact lens temporarily reshapes the top layer of the cornea.  This reduces myopia (short-sightedness), hyperopia (long-sightedness) or astigmatism so that you won't have to wear glasses or contact lenses during the day.

The degree of correction achieved varies depending on your prescription. We can advise on the degree of correction at your appointment.

Is it safe?

If it is properly handled and good hygiene is maintained, it does not pose any extra risk compared to a normal soft contact lens. There is no minimum age for a child to wear these lenses, as long as contact lens care procedures are followed with or without adult supervision.

Does it really stop me from getting more short-sighted?

According to current research, patients with orthokeratology treatment progressed at about 50% of the rate compared to spectacle wearers on average. However, results may vary from person to person as each individual responds differently.

Benefits of Ortho-K

  • Gently and gradually reshapes the surface of eyes to correct refractive error.

  • Gives excellent day time vision.

  • Great for screen workers who suffer from dry eyes, especially in air-conditioning with regular contacts, and don’t want to wear spectacles.

  • Great solution for people who work or play in dusty/dirty environments, those who engage in water sports or contact sports.

  • Save money over the long term on purchasing contacts and glasses.

  • New studies suggest that myopia progression in children can be slowed or stopped with the use of Ortho K lenses.

  • Just as safe to use as other over-night contact lenses.

Imagine no more glasses or contact lenses during the day…  You have this option right now!

Central Corneal Stainings

In early 2018, a 12 years old Asian boy came in for a routine ortho-k checkup. He came from overseas and had been wearing ortho-k lenses for myopia control for 5 years. He was using his fourth pairs which was 4 months old. He mentioned blurry unaided distance vision with his right eye. His mother reported that the practitioner had to prescribe the lens which under-corrected the moderate myopia of his right eye; it was because the lens which could fully correct his myopia caused corneal issue. My examination found that his eyes were normal and the condition of his lenses were good.

In early 2019, he needed new lenses and I fitted him with custom design lenses in order to fully correct his vision. After wearing the new lenses for 5 weeks, his right eye developed central corneal stainings which required lay-off of the right lens and used topical antibiotic medication for a few days, and then refitting the right lens with different parameters in order to avoid the same problem in the future. After using the remade lens, only trace corneal stainings were found occasionally in subsequent check ups and no medication was required. 

In mid 2020, his lenses needed to be replaced again and I tried different lens design. Since then, there has been no significant corneal staining problem till last visit in April 2021. The patient and his parents were happy about the result.

In fact, his sister had the similar issue, management and successful outcome as her brother.

The photos of the patients were taken in Jan 2021.


Guide: Experienced and dedicated orthokeratologists and therapeutic optometrists who are certified to fit different lens designs, including custom designs, related problem solving knowledge and skill, and also most updated information. In addition, sufficient related good quality equipment is very important, such as slit lamp imaging and gold standard corneal topographer, e.g. Medmont E300. Good outcomes require trust, understanding, patience, co-operation and long-term commitment from practitioner, patient and parents.

Irregular Cornea and Residual Power

A middle aged Caucasian male was referred to me by his previous ortho-k practitioner in another state because another optometrist in Perth could not correct the distance vision of his left eye after about 6 to 8 visits recently. He had been using ortho-k for about 4.5 years. His left eye could achieve 6/6- with residual power +0.50DS/-1.00DCx105. The patient reported slightly blurry vision and would like to see better.

I fitted him with an advanced custom design ortho-k lens and helped him to achieve 6/4.8p with minimal 

residual power after wearing the new lens for about 7 weeks. He was very pleased with the result.
