Dry eye after LASIK

Dry eye syndrome refers to a substandard tear film because of reduced volume of tears or too fast tear evaporation. The disease gives rise to a lot of symptoms equivalent to burning, itching, foreign body sensation, high sensitivity to light, graininess, and other eye problems.

The tear film has three components: an outer layer of fatty substances secreted by the meibomian glands, a center layer of watery tears produced by the lachrymal glands, and an inner layer of mucous produced by the goblet cells within the conjunctiva, the interior lining of the eyelids.
Symptoms of dry eye could be experienced as a result of deficient aqueous tears production, more rapid evaporation (as a result of inadequate lipid secretions), or mechanical causes together with poor blink distribution. With the rising approval for surgery to regard refractive errors within the eye, particularly LASIK, there incidence of dry eye has risen.
LASIK (laser in situ keratomileusis)
Laser-based refractive surgery has several common approaches, but there may be greater preference for technique is LASIK. Corneal realignment is the first objective of refractive surgery. Just a normal cornea can bend light rays properly toward the retina to enable properly focused vision. Once the cornea is correctly aligned, light is focused to hit directly onto the retina, correcting problems of vision and removing the necessity for contact lenses or spectacles.
You may commit to have LASIK surgery since you want spectacles and speak to lenses. You’ve got become weary of wearing and taking good care of the contacts, and spending money on replacements and cleansers. Besides, long-term use of contact lenses can have caused dry eye symptoms. Unfortunately, dry eye syndrome may be just as present, and just as painful, after LASIK.
LASIK surgery has high impact, inflicting damage at the nerve network serving the cornea. It’s important to chop out a flap within the centre of the cornea, slicing in the course of the outer layer (epithelium) of the cornea to arrive the internal layers (stroma). It can be crucial to burn a tiny patch of inner tissue with the laser, with the intention to reshape the cornea. The surgery takes only some minutes, with very little pain or discomfort during surgery.
It is extremely likely you’ll suffer dry eye problems within the first month after LASIK. But as healing proceeds over the years, the dry eye problems lessen, and are fully resolved after about six months. This, obviously, is the target. For a lot of, however, the dry eye remains; for some, it may worsen.
Dry eye syndrome can emerge after surgery because of many factors. Some corneal nerves are severed during surgery, causing the cornea to lose sensation (here’s called LASIK-induced neurotrophic epitheliopathy, or just LINE). The lack of sensitivity deadens the triggers for the lachrymal glands and deactivates their capability to secrete tears, so aqueous tear production abates. an analogous interruption happens to the nerve impulses that induce stimulate lipid secretion inside the meibomian glands. The standard blink can be adversely affected, in addition the mucous secretions of by the goblet cells for the tear film. The final effect is an inferior quality tear film and a cornea with a flatter curvature and reduced capability to preserve an absolutely protective tear film.
Management of Dry Eye after LASIK
Even before actual LASIK surgery, dry eye management should already be done. During prepatory preparations, the physician should discover if you’re already showing signs or symptoms of dry eye disease, including blepharitis, contact lens intolerance, etc. Any eye medical conditions existing before surgery can magnify the post-operative effects of LINE. Ideally, these symptoms need to be completely resolved before surgery occurs.
The doctor might also prescribe artificial tears to give added lubrication to the attention. However, the mainstay of treatment is topical cyclosporine in a castor oil base. Here’s usually applied both before and within the months after LASIK surgery. Taking omega-3 fatty acid supplements can be advised, especially where the patient just isn’t responding well to topical cyclosporine or the the drugs isn’t available.

Makeup for Glasses
Glasses are sexy, fun and cute depending on our personality. They can do more than help us see clearly =D. They can also be accessories for our eyes (and face). I have been short sighted since I was 11 years old. Without glasses/contact lenses; everything is blurry to me. Being in Hong kong, I know so many girls AND guys who don't even need glasses WEAR glasses. Why? Because glasses are incredibly stylish! They are becoming a fashion accessory as well as a functional product. I am definitely a lot more inspired to wear my glasses now. A lot of you guys feel its pointless wearing makeup since eyes tend to disappear behind the frames. However, its your glasses that make your eyes focal point of your face. A little makeup goes a long way to help them pop from behind the lenses. To be honest- the type of makeup can depend on the type of frames you have. Actually- you can wear whatever look you want. There shouldn't be a certain rule. There can just be suggestions and guidelines. I wear thicker frames because I find them very arty & stylish. But its the thick frames that really make the eyes hinder/disappear. Glasses wash out the eyes. But you don't need super amounts of eyeshadow to help your eyes stand out. Neat groomed eyebrows, eyeliner and lip colour is really all you'll need for all of your facial features to stand out equally. This tutorial doesn't mean this is the only way to wear your makeup. It is just how I like to wear it and perhaps maybe a look you can try out
