Orthokeratology (Ortho-K): Correct your vision while you sleep.... I swear it's not some voodoo ancient ritual thing

11/28/2017

Orthokeratology (OrthoK) is the science of reshaping the cornea to correct ametropias (nearsightedness, or myopia, farsightedness or hyperopia and astigmatism).

The way it works is as follows: Your eye doctor designs a corneal mold (similar to a gas permeable lens )based on your eyeglass prescription and your corneal shape. The corneal mold is then inserted before bed, and reshapes the cornea to correct your vision while you sleep! The molds are then removed in the morning and the wearer can enjoy great vision throughout the day without wearing contacts or glasses.

OrthoK has been around for longer than LASIK, and for those who aren't a candidate, or who aren't interested in the permanent risks of the procedure, OrthoK may be a viable option to correcting your vision.

The real magic of OrthoK is in the great ability of the mold to slow the progression of myopia (nearsightedness). Traditional glasses in kids do correct the central vision, however they create a farsighted peripheral defocus on the retina that stimulates the eye to grow longer over time to "catch up" to the peripheral defocus. The figure below explains this pretty well.(http://www.cvs.rochester.edu/yoonlab/research/mpc.html)

OrthoK induces a myopic defocus in the periphery of the retina to help slow progression through the incorporation of a reverse or relief curve in the corneal mold (red ring featured below). This curve is what slows down the myopia and isn't possible to create with soft contacts or glasses at this time (development with soft lenses is happening, but is won't be customizable like our OrthoK designs).

The initial cost of OrthoK is certainly higher than that of soft contacts or glasses, but is only a fraction of what someone would spend on LASIK. The other great thing about OrthoK is that we can adjust the curvature of the molds overtime to account for the onset changing visual needs for those over 40 who are struggling with their near vision also. We can adjust one eye for near vision (monovision) or adjust both (multifocal).

If you'd like to discuss OrthoK more or are unsure of whether or not you're a good candidate, give us a call.

See well friends,

Dr. Schott

What our patient's say

"I've been going to Maitland Vision Center since the 80s and have always been happy with the great office staff and Dr. Willson. This week I had my first appointment with Dr. Schott who has taken over after Dr. Willson's retirement and I couldn't be happier with the new guy! Looking forward to many more years of great care. (PS: I was disappointed when Dr. Willson phased out his optical (eyeglasses) center some years ago, but was happy to learn that Dr. Schott plans to bring it back.)"

I never took into account the fact that LASIK is actually newer than Ortho-K, because the latter has been around longer. I will ask optometrists about these treatments to know which one would be the best for me. It will help me keep good eyesight even when I reach my senior age which I want to achieve in the long run.

I want to use this opportunity to testify of the marvelous work of Dr. Odunga and how he has helped me in curing my sickness and bringing happiness into my life. I can really vouch for Dr. Odunga in herbal treatment. I was suffering from Cervical Cancer and infected with HPV 16. I used to have unusual vaginal bleeding and painful urination. There was nothing I could do until a childhood friend introduced me to Dr. Odunga Remedies. I spoke with him and ordered his recommended medication which was delivered to me through DHL. Immediately I began using herbal medicine, and within a week I couldn't feel any pain. It took me 2 weeks to finish the medicine and afterwards I was completely cured. I highly recommend that you order your herbal medication through Chief Dr. Odunga. Contact his email [email protected] OR What'sApp/Call him at +2348167159012

He is 100% reliable to help you too

GREAT WHIP RECOVERY CYBER SERVICES THE BEST IN ONLINE RECOVERY
I’m Kim Tremblay living in Toronto, Canada. I’ve always been careful with my money until one night I stumbled onto a sleek website offering Guaranteed Bitcoin Doubling. The site looked professional. The testimonials sounded real. I invested $640,000 in Bitcoin hoping it will double the amount the company told me. Hours passed, the website stopped responding, customer support vanished and right there, I realized I’ve been scammed. I couldn’t sleep that night.
In the morning, I searched frantically online on how to recover scammed Bitcoin, then I came across GREAT WHIP RECOVERY CYBER SERVICES and saw testimonials of how it has helped people recover bitcoins by online fraudsters. I contacted the agency and gave them all the necessary information about my transaction, after 72 hours they called me to inform me that my money had been recovered.

CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK.

My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company. I had invested heavily during a time when Bitcoin prices were rising, thinking it was a good opportunity. Unfortunately, I was scammed out of $120,000 AUD and the broker denied me access to my digital wallet and assets. It was a devastating experience that caused many sleepless nights. Crypto scams are increasingly common and often involve fake trading platforms, phishing attacks, and misleading investment opportunities. In my desperation, a friend from the crypto community recommended Capital Crypto Recovery Service, known for helping victims recover lost or stolen funds. After doing some research and reading multiple positive reviews, I reached out to Capital Crypto Recovery. I provided all the necessary information—wallet addresses, transaction history, and communication logs. Their expert team responded immediately and began investigating. Using advanced blockchain tracking techniques, they were able to trace the stolen Dogecoin, identify the scammer’s wallet, and coordinate with relevant authorities to freeze the funds before they could be moved. Incredibly, within 24 hours, Capital Crypto Recovery successfully recovered the majority of my stolen crypto assets. I was beyond relieved and truly grateful. Their professionalism, transparency, and constant communication throughout the process gave me hope during a very difficult time. If you’ve been a victim of a crypto scam, I highly recommend them with full confidence contacting:

All you need is to hire an expert to help you accomplish that. If there's any need to spy on your partner's phone. From my experience I lacked evidence to confront my husband on my suspicion on his infidelity, until I came across ETHICALAHCKERS which many commend him of assisting them in their spying mission. So I contacted him and he provided me with access into his phone to view all text messages, call logs, WhatsApp messages and even her location. This evidence helped me move him off my life . I recommend you consult REALCYBERHACKERS AT gmail com or whatsapp +14106350697 if you need access to your partner's phone or any kind of hacking, they carry out all kinds of hacking job

"In the crypto world, this is great news I want to share. Last year, I fell victim to a scam disguised as a safe investment option. I have invested in crypto trading platforms for about 10yrs thinking I was ensuring myself a retirement income, only to find that all my assets were either frozen, I believed my assets were secure — until I discovered that my BTC funds had been frozen and withdrawals were impossible. It was a devastating moment when I realized I had been scammed, and I thought my Bitcoin was gone forever, Everything changed when a close friend recommended the Capital Crypto Recover Service. Their professionalism, expertise, and dedication enabled me to recover my lost Bitcoin funds back — more than €560.000 DEM to my BTC wallet.
