Simply using regular prescription contact lenses, particularly if they are soft contacts which is what most people wear, increases your risk of serious infections such as corneal ulcers. If they are worn overnight, the risk goes up even higher. Extended wear contacts? The risk goes up even more.
But patients who need to see are willing to accept some of these risks so that they can function.
Someone who just wants their eye color to be different is taking a significant chance of harm to their eyes for a cosmetic reason. This risk can be much higher for people who get these colored contacts from novelty stores or places that don't take the time to ensure a proper fit.
Bottom line: colored contact lenses are not advisable, especially for younger people. If an adult still insists on getting these, they should at least see an eye doctor such as an optometrist to ensure that they are getting a health product and that it is properly fitted and maintained and subject to proper followup exams.
Sun exposure to the eye is associated with macular degeneration - in people who have a hereditary tendency - cataracts, growths on the eye (pterygium and pingueculum) as well as cancers of the superficial layers of the eye and the eyelids.
The only thing I would have checked is that he does not do that because his eyes are sensitive to light, because that can indicate a possible problem.
So, as long as everything - including his vision - checks out as normal and he is just doing it to be fashionable and he is not using them inappropriately (in the classroom for instance) but mostly when outside, then this should not affect the eyes negatively.
Periodic checkups will insure that this is the case. There are studies that suggest that exposure to blue wavelengths of light during childhood - such as what is in natural sunlight - are associated with a decreased incidence of myopia (near-sightedness). So, if there is a family tendency to be myopic, then at least some time outdoors exposing the eyes to natural light would be in order.
Another cause of contact lens intolerance is allergies to either something external or to the lens or lens solutions or cleaners. This will usually have tell-tale signs on examination so the doctor that prescribed the contact lenses should be able to tell you. If they are not sure you can request to be referred to a cornea specialist.
Some clues that this is probably allergic conjunctivitis: history of other allergy signs (itchy nose, sneezing, asthma-like symptoms, constant rubbing of eyes, pets in the house, seasonal occurrence
Clues that this is more likely infectious conjunctivitis: acute (sudden) onset, usually starts in one eye, mucus discharge (pus-like), fairly swollen lids (which may swell shut), extremely bloodshot (might even have splotches due to broken blood vessels, pain, light-sensitivity, cases of pink-eye going around the school or community.
If it is allergic, using topical allergy eyedrops and/or antihistamine like Benadryl, cold compresses, it will usually be better the next day.
If it is infectious conjunctivitis, it will get worse before it gets better, no matter what you treat it with. Note that, although primary care doctors will usually prescribe them, antibiotic drops will not cure most cases of conjunctivitis since they are due to viruses (which are not affected by antibiotics) and not bacteria.
In infants or children under 2, it is not inappropriate to use antibiotics as protection against bacteria which can coexist in infections since children this age don't have the same immunity.
In either case you can use a decongestant/antihistamine drop such as Naphcon-A up to 4 times a day. Again, if it is allergic it will get better pretty quickly. If it is an infection, it will get worse before it gets better and can last up to a week. In severe cases, the eye doctor might prescribe steroid drops but this should be used with extreme caution as it can cause glaucoma and other possible complications.
Children should be kept from school if they have an infection or if the parents aren't sure.
Alas, this is not the case. It is a normal part of aging and cataract surgery has been around since the time of the Egyptians, who would 'couch' or push the cataract into the back of the eye and to the side with a sharp reed (since there was no way to remove it surgically in those days).
Nowadays, it is one of the most common procedures performed in the world and is extremely safe with a very low complication rate. It has also been shown improve the quality of life in elderly people as well as decrease the rates of accidental falls and fractures, as well as depression.
In good hands and at a reputable place, he has an excellent prognosis. If his diabetes is controlled, it usually does not have a bearing in most cases.
If you are only 10 days out, I would not be overly concerned. You should be using frequent preservative-free artificial tears. And you should be asking your surgeon for recommendations specific to your situation. He or she knows your eyes a lot better than I do!
If the prescription is correct then it is unlikely to cause an increase in your eye power.
If you are near-sighted (myopia) and your prescription is too strong, it is possible for it to contribute to an increase in the eye power if your eye is still developing. This development usually stops around the age of 25.
If you are far-sighted (hyperopia) however, then it probably won't make too much difference. If the prescription is too strong, your eyes won't have to work as hard and they will get used to the glasses as a 'crutch' and you might find that you are more dependent on the glasses than you were before. But that doesn't necessarily mean that your eye power has changed.
Restasis works by blocking the white blood cells which are involved in inflammatory dry eye disease. Since these cells have about a 90-day lifespan, it can take anywhere from 3 months to 6 months for Restasis to reach a therapeutic level. Sometimes when patients tell me that they tried Restasis and "it didn't work" they were usually not on it long enough for it to count.
Likewise, if you stop Restasis, it might take a month or longer before you know for sure if the effect has worn off.
If you have been on it for years without a problem and now you have an issue with one of the eyes, Restasis is unlikely to be the culprit. But your eye doctor should review what other medications you are on. Again, it is unlikely that you are on something comparable to Restasis already so I would be hesitant to just stop it without doing some investigating as to the cause of your symptoms.
It is also possible that despite being on Restasis that your dry eye disease is nevertheless progressing. There are many contributing factors to dry eye including auto-immune diseases, diet, environment, skin type, genetics, other drug side effects, to name a few. Restasis alone might be insufficient to counteract these other causes.
To answer your question, yes it is safe to stop Restasis. But if your symptoms worsen - and this might not happen for several weeks - and you need to go back on Restasis, just be aware that you will have to start all over again as it can take several months to reach a therapeutic level again.
In most cases, this applies to patients with myopia (near-sightedness). If she has hyperopia (far-sightedness), this can continue to increase for a longer time and so she might not be a candidate even after she is fully grown because the refraction is not stable.
Exceptions are made in children for when one eye is much weaker than the other and is at risk for losing vision (amblyopia). This is typically done at an academic center after careful consultation and review by pediatric ophthalmologists if all other options have been exhausted.
The confusion comes from the fact that most people will develop scarring of the posterior capsule - the sac that holds the intraocular lens implant placed inside the eye. The symptoms are very similarIn the old days this was called an 'after cataract'. Some eye doctors may still use similar terminology but it is not a cataract, simply scar tissue.
It is easily removed with a YAG laser, completely painless, safer than the original cataract surgery and there are no restrictions after the procedure.
Studies have shown that these nerves regenerate over a period of several months to sometimes as long as a year. This can be more sigfnicant if a patient had a dry eye problem to begin with so most LASIK surgeons will be diligent about identifying those patients with dry eye and treat them aggressively prior to the procedure in order to ensure an optimal outcome. Fortunately it is only a minority of patients who have a persistent, serious dry eye problem after LASIK.
Many cases of dry eye are actually due to an instability of the tear film due to a deficiency of oil due to meibomian gland dysfunction. This is often overlooked by eye doctors who don't specifically look for it. So in addition to using artificial tears - and I would recommend using preservative-free artificial tears for the first several weeks after surgery - you also want to promote adequate oil production from the eyelids.
Some things to try:
- preservative-free artificial tears
- moist heat on the lids (but avoid pressure on or rubbing of the eyelids for the first month)
- take fish oil, flaxseed oil, or black currant seed oil (the latter can be found in a supplement called HydroEye)
- cut wheat out of the diet =3D Paleo Diet. Wheat has been linked to inflammation and autoimmune disorders including dry eye due to decreased tear production
- limit omega-6 oils - these are found in fried foods and most processed foods and listed as hydrogenated oils and fats and are also linked to inflammation
- make sure you don't have a ceiling fan or AC duct blowing on you at night. Even a fan in the corner of your room can be blowing enough to dry your eyes out
- if fans or AC are not an issue, consider using a lubricating gel or ointment at night to keep the eyes from drying out while you sleep
- if you are still struggling, you might benefit from Restasis, a prescription eye drop that decreases inflammation and can increase tear production. Be aware that this medicine can take a few months to reach a therapeutic level.
Bottom line: dry eye is common early after LASIK and usually improves with time. But you should discuss your symptoms and concerns with your surgeon. Untreated dry eye is associated with regression which can lead to undercorrection of your refractive error. So your doctor will want to know so they can address it properly.
Some things that can irritate the eyes at night include allergens such as dust/dust mites/animal dander/perfumes or dyes from detergents used on bedding/etc, the eyes cracking open while you are asleep and they are drying out, a ceiling fan or AC blowing on the eyes.
Could it be that the eyes are irritated during the evening? Staying up late watching TV or using the computer? Drinking alcohol late? These would be some other possibilities to consider.
Try to eliminate possible allergic irritants. Put some lubricating gel or ointment in the eyes at bedtime and also consider wearing a sleep mask to keep the eyes from drying out.
If these options don't do the trick, then you should definitely see an eye doctor to rule out other causes.
