What are the precautions for orthokeratology lenses, and what are the precautions for wearing orthok

1. The lenses must be cared for with a special rigid gas permeable contact lens care solution, and it is forbidden to use any other liquid (such as tap water, cold boiled water, normal saline or soft contact lens care solution, etc.) to care for the lenses, otherwise the service life of the lenses will be affected; It is forbidden to clean lenses with other substitutes such as detergent and soap, and it is forbidden to disinfect lenses with alcohol and other substitutes.

Ophthalmologist Shi Yongli Profile: Director of the Department of Ophthalmology, working in a tertiary hospital for more than 10 years, good at cataract, glaucoma, pterygium surgery and various ocular surface diseases, dry eye syndrome, keratitis and pigmentitis, fundus disease, various complex eye diseases, systemic diseases, ocular complications and difficult diseases.

Orthokeratology lenses require a rigorous eye examination. The main purpose of the inspection is to understand whether the wearer is suitable for wearing orthokeratology lenses, and to provide a parameter basis for choosing the right lens and the best wearing effect. The examination items include visual acuity examination, slit lamp microscopy, fundus examination, intraocular pressure measurement, ocular position examination, measurement of various eye parameters (cornea, pupil diameter, eyelid characteristics), comprehensive optometry, corneal topography, endothelial cell microscopy, etc.

How to wear:

Precautions before wearing.

1. Trim your nails that are too long to avoid damaging the lenses.

2. Wash your hands with soap, especially the fingers that touch the lenses.

The glasses method uses the index finger and thumb of the side hand to open the eyelids, the position of the fingers is as close to the eyelid margin as possible, the lens is placed on the index fingertip of the other hand, the lens is gently worn on the cornea**, the lower eyelid is released first, the upper eyelid is released, blink gently, and make sure that the lens is worn on the cornea in front of the mirror.

Prepare before wearing glasses.

1. Cut off excessively long nails.

2. Put a wash basin in the sink to prevent the lenses from being washed away by water.

3. Wash your hands twice with soap (yellow transparent laundry soap), especially the fingers that touch the lenses should be rinsed repeatedly.

4. Put a clean white towel in front of the mirror on the operating surface to avoid scratches after the lens falls off.

1. Take the lenses out of the case and rinse them with cool boiled water, and put them on the tip of the index finger of your right hand on the concave side.

2. Use your left finger to pull open the upper and lower eyelids, and the position of the fingers should be placed in the middle of the medial and lateral canthal angles and close to the root of the eyelashes to ensure that the cornea is completely exposed.

3. Look at the mirror in front of you with both eyes, aim the lens with the right index finger at the cornea, and gently place the lens on the cornea**. After confirming that the lens is in the middle of the cornea, slowly release the finger pulling the eyelid, and close the eye for about 3 seconds. If the lens is worn at the bulbar conjunctiva, use the suction stick to suck out the lens in time, rinse and wear the lens again; Wear the lens on the other eye as described above;

4. After each time you wear glasses, pour out the care solution in the mirror box and wash and disinfect it with hot water, and put the lens box buckle on a napkin to dry for the next use.

5. Orthokeratology lenses should be worn before going to bed, and the time of wearing the lenses should be 8 to 10 hours a day.

1. Wash your hands thoroughly with transparent soap.

2. Pour a little care solution into the lens box to prepare for the lens.

3. Before taking off the lens, put the moisturizer into both eyes and blink, and then take the lens after sliding on the cornea.

4. Pull the eyelid apart to fully expose the cornea, aim the suction stick at the outside or slightly below the lens, and suck the lens out after it is fully in contact with the lens. Remember not to pull the lens vertically at the cornea** to avoid damage to the cornea.

5. Clean the removed lenses with care solution or cleaning solution, rinse them with cold boiled water and put them into the lens box with the concave side facing up, and then add the care solution to completely submerge the entire lens and close the lens box. Soak the lenses for 6-8 hours a day.

6. After use, the suction rod can be rinsed with cool boiled water, wiped dry, and the suction stick box should be kept dry to avoid breeding bacteria.

7. After taking off the lens, apply antibiotic eye solution (Telbital) and corneal repair eye solution (chondroitin sulfate), with an interval of 5 10 minutes between the two drugs, 2 times a day. Routine use during the shaping period, 1-3 times a day depending on the amount of secretions, can be used for backup or discontinuation after the end of the shaping period.

1. Cut off excessively long nails.

2. Put a filter on the drain of the wash basin to prevent the lenses from being washed away by water.

3. Wash your hands with soap three times, especially the fingers that touch the lenses should be rinsed repeatedly.

4. Put a clean towel in front of the mirror on the countertop.

5. Open the lens case. Open both eyelids with the index finger and thumb of the side hand wearing the glass, the position of the fingers is as close to the eyelid margin as possible, place the lens on the tip of the index finger of the other hand, gently wear the lens on the cornea**, first release the lower eyelid, after releasing the lower eyelid, blink gently, and make sure that the lens is worn on the cornea in front of the mirror.

Note: You can place a mirror in front of your eyes, when wearing glasses, you should open your eyes at the same time, let your eyes fix in one of the glasses, control the rotation of the eyeballs when wearing glasses, in addition, to ensure that the lenses are placed firmly on the cornea, you can slowly release the fingers that pull the eyelids, and let go too early may make the lenses offset or fall off. In addition, the soaking time of the lens must be more than 4 hours before wearing.

It is necessary to make an examination and evaluation to determine whether it is suitable to wear orthokeratology lenses, including refraction, corneal curvature, corneal topography, corneal thickness, intraocular pressure, etc., which cannot be judged by just one prescription!

Orthokeratology glasses are rigid contact lenses and have high safety requirements. Mild myopia and astigmatism are best matched with targeting, and you may wish to go to the space to learn about the relevant methods, which have relative advantages in myopia and correction of astigmatism.

As a work in pediatric ophthalmology, I don't recommend you to wear orthokeratology lenses, because your astigmatism is a bit big, I don't know how much your cornea is scattered, but I recommend that you can come to us to see, you need to do a lot of tests before getting orthokeratology lenses fitted to see your test results to determine whether you are suitable or not!

You can go to your local orthokeratology lens fitting facility for a detailed examination before making a decision. The doctor will give you a detailed answer. You can also go to the local science and technology film shaping lens chain organization for consultation.

There is no age limit for orthokeratology lenses. There are two main functions: first, you don't need to wear any glasses during the day, and you can see very clearly (children do not affect outdoor activities); 2. Slow down the progression of myopia and avoid becoming high myopia and causing some eye diseases.

Not all people can wear it, first do a strict eye examination to see if the conditions are suitable for wearing, if it is suitable, you can try it on to see the correction effect. You can come to the ophthalmology department of Beijing Children's Hospital to have a free trial every morning from 1 to Friday, you can go there first to try it.

Don't bring what you usually see, and bring glasses if you can't see.

Orthokeratology lenses are divided into three groups: below 300 degrees, 300 500 degrees, and 500 600 degrees. The lower the prescription, the lower the fee, and people with low myopia are encouraged to accept ** as soon as possible to control the progression of myopia and achieve better shaping results.

At present, the domestic fee is about 4000-7000 yuan. Bi Xiaohong, reporter of this newspaper, expects the effect of wearing orthokeratology lenses After correction (after 1-2 weeks), the naked eye visual acuity decreases.

Below 300 degrees is raised to or above 90%.

300-500 degrees to or above 80%.

500-600 degrees to or above 70%.

<>1. It is necessary to pay attention to the wearing of orthokeratology lenses, the time of wearing lenses is 8 to 10 hours a day, and it is necessary to check whether the position of the lens is located in the cornea** after wearing the lenses. Do not use eye drops when wearing glasses, and do not wear the lenses backwards and sides.

2. The lenses are relatively fragile, do not squeeze the lenses too hard, and do not rinse them with hot water. At the same time, it is necessary to replace the lens case and suction stick regularly, and use it according to the doctor's instructions. Wear it correctly, wear it as required, and don't wear it if it's not suitable.

Orthokeratology lens wearing process:

1. Please cut your nails short and trim them smooth.

2. Please wash your hands carefully with hand sanitizer or soap, and rinse the foam on your hands thoroughly.

3. Lenses are conventionally divided into two colors.

4. When taking out the lens, dip the index finger of the right hand into the concave surface of the lens and place it in the palm of the left hand.

5. Drop 2-4 drops of care solution on the concave surface of the lens, use the ring finger of the right hand to scrub radially from the center to the outside for 20-30 times, and then rinse the care solution on the lens with normal saline until the lens is not slippery.

6. Hold up the lens with the index finger of your right hand and place it in the best position on your fingertips, and drop 1-2 drops of artificial tears on the lens (Note: Before applying eye drops to the lens, check the lens to confirm whether the lens is intact, whether there are serious scratches and cracks, if so, please stop wearing it immediately.) ）

7. Use your thumb and index finger to open your eyes to the maximum, or the middle finger of your left hand is on the top, the vertical eyelids fix the upper eyelid eyelashes in the upper eye socket, the right index finger holds the lens, and the middle finger is slightly bent to fix the lower eyelid below and blink until you blink.

8. After the lens is placed on the black eyeball, first release the upper and lower eyelids, and then close the eyes.

9. After wearing the glasses, please pour out the care solution in the lens box, rinse it with normal saline, and open it to dry.

10. Before taking off the lenses, wash your hands thoroughly and check whether the lenses are on the black eyeballs.

11. Before taking off the lens, put 1-2 drops of artificial tears in each eye, lubricate for 3-5 minutes, then drop 1-2 drops of artificial tears, gently push the lower edge of the lens with the lower eyelid, confirm that the lens has slipped and then take it out with a suction stick.

12. When using the suction stick, rinse it with normal saline first.

13. Use your thumb and forefinger to open your eyes to the maximum, and hold the suction stick with the other hand, perpendicular to the periphery of the lens, and take off the lens after sucking.

14. When removing the lens from the suction stick, hold the lens with your thumb and move it parallel to the side, and do not forcibly remove the lens.

15. After removing the lenses, please clean the lenses repeatedly.

16. Pour the care solution into the case, slowly put the lens into the case, and confirm that the lens is in the center of the case, so as not to crush the lens when the lid is covered.

1. The whole process of operation should be completed on a tabletop, and you must not walk back and forth with the lens. Stick to the edge of the table during the fitting process to prevent the lenses from falling to the floor. It is recommended to spread a white towel on the table to prevent the lenses from falling and being damaged.

2. Be sure to clean your hands when operating in the morning and evening, long nails are easy to scratch the edge of the lens to form damage and cause fragments, and you should trim too long nails in time to avoid scratching the lenses.

3. This product should not be in contact with other chemicals, otherwise it will contaminate or damage the lens, such as: mascara, eye shadow, cream, hand cream and non-special care products.

4. Avoid placing flowers and plants on the operating table, so as not to cause pollen to fall into the mirror and box.

5. Although the lens has a certain toughness, due to the temperature difference between day and night, the brittleness of the shaping lens increases, so the lens should be scrubbed evenly, and the force should not be too large. So as not to deform and crack the lens. If the water temperature for cleaning the lenses is too high, the lenses will be deformed, causing the comfort and fitting to deteriorate, but the water for rinsing the lenses can be used at the turn of the season, and the water temperature can reach the temperature of the hand, so do not overheat.
