Did your eyesight fall behind right after school started? Are your kids who wear OK glasses getting their vision checked carefully?

Before the start of school, many children who wore orthokeratology lenses delayed their follow-up examinations for various reasons. As soon as the school started, the clinic welcomed the first wave of "divine beasts" who could not see the blackboard clearly!

Once you start using orthokeratology lenses, it does not mean the end, but the beginning!

Follow-up examination is the most important part of the entire medical process after fitting glasses!

Regular check-ups can help early detection and early treatment of any problems that may arise while wearing glasses, so it is very necessary! !

The "Expert Consensus on the Fitting Process of Orthokeratology Lenses (2021)" lists the following item separately under "Indications and Basic Conditions": "Being able to understand the mechanism of action and actual effects of orthokeratology lenses, having good compliance, and being able to go to medical institutions for treatment in a timely and regular manner as required." In other words, if you cannot correctly understand the pros and cons of orthokeratology lenses, and are always unable to do regular checkups because you are "too busy studying and have no time", then we do not recommend that you wear orthokeratology lenses!

1. How to correctly understand orthokeratology lenses?

Orthokeratology is a hard corneal contact lens with reverse geometric design as its main feature. It is worn at night to flatten the curvature of the central area of ​​the cornea within a certain range, thereby temporarily reducing the degree of myopia and improving daytime naked eye vision. Based on long-term fitting practice and many clinical studies, it has been found that orthokeratology can effectively slow down the progression of myopia in children and adolescents.

2. Correctly understand orthokeratology lenses

The above advantages have led to an increasing number of people wearing orthokeratology lenses. However, orthokeratology lenses also have risks, including corneal epithelial damage, conjunctival irritation, dry eyes, etc. in mild cases, corneal infection, increased irregular astigmatism, etc. in severe cases. The only way to discover and avoid these risks in a timely manner is to go to a qualified medical institution, undergo standardized examinations and trial wear, test the lenses that match the lens, and wear them under the strict supervision of a doctor or fitter.

3. Why is regular check-up necessary?

The review during the wearing period mainly focuses on the following two aspects:

(1) Safety: Regular review can detect problems in wearing as early as possible and deal with them in a timely manner. Slit lamp examination can evaluate the wearer's ocular surface health, lens fitting status, and lens care; corneal topography can monitor changes in corneal morphology and detect lens deviation in a timely manner. At the same time, by asking patients about their wearing habits and care details, errors can be corrected in a timely manner and targeted wearing guidance can be given.

(2) Effectiveness: Evaluate the wearing effect of orthokeratology lenses based on the main purpose of wearing them for different patients: For adults in the stable refractive period, the main purpose is to evaluate the daytime naked eye vision and visual quality; for adolescents and children in the progressive refractive period, regular testing of changes in axial length and refractive power (eye test with lenses) is required to evaluate the effect of myopia control.

In addition, check whether the lens has scratches, sediment contamination, damage or deformation; check the lens fit: check the fluorescent staining while wearing the glasses, observe the tightness of the lens, whether the positioning is centered, and whether the lens mobility is appropriate.

After listening to the above explanation, those babies who have not had follow-up examinations on time or have been wearing glasses for too long should come to the hospital for follow-up examinations as soon as possible!
