You might experience dry eyes after Lasik so as other patient. When you are facing the problem of dry eyes it may causes itch, sting tear up. There are some side effects of LASIK eye surgery and they may recover within a year for majority of patients. Experts on eye said that eight out of ten patient face dry eyes symtompts after LASIK surgery following the week.
Why LASIK creates dry eyes:
After taking LASIK surgery dry eyes can be caused by the surgery how it enhances vision. The main action of LASIK surgery is to reshaping the cornea to improve vision, but it may hamper the tear film by altering the curvature of the cornea. After the LASIK surgery you may face the problem of dry eyes because of the creation of a corneal flap or ablation, or removal of corneal tissue that might affect corneal nerve fibers to tear production.
It does not always mean that LASIK creates dry eyes problem. One can experience dry eyes before LASIK. In this type of situation patients should inform their surgeons about the conditions before having laser eye surgery. Then your surgeons give you proper treatment on your problem.
How you identify symtompts of dry eyes:
There are some common symptoms of dry eyes such as mild ocular irritation to severe discomfort, photophobia and vision loss. In clinical explanations of dry eye involve the indication of reduced aqueous tear production, reduced tear volume on the ocular surface, increased rate of tear evaporation, and increased tear osmolality. There is frequently a gap noted in the middle of the severity of signs and symptoms in patients with dry eyes.
Symptoms that should be elicited include feelings of dryness, grittiness, irritation or tired eyes. It is also of value to inquire about vision fluctuations, especially in conjunction with blinking, and any eye symptoms that seem worse towards the end of the day. Patients should be appropriately counselled with realistic expectations about the immediate postoperative worsening of dry eyes and the potential for long-term symptomatic postoperative dry eyes.
It is a problem to diagnose dry eyes for common patient. For those they should inform a good trained eye doctor who can measure the intensity of dry eyes problem. But in few case, doctor might decide that your illness is too severe and that you are noteligible for LASIK treatment. Laser eye surgery is often not a good idea for patients with unmanaged dry eye syndrome because the LASIK procedure can cause further drying of the eyes.
Treatment of LASIK dry eyes:
The treatment of dry eyes problem can be given in some ways. If you go to your doctor he might suggest you preservative-free artificial tear drops. If you have the problem of keratoconjunctivitis sicca, or dry eye syndrome, doctor may prescribe you topical cyclosporine eye drops for additional relief.
Generally it has been seen that many patient get good recovery from post-LASIK dry eyes problem with conventional treatments. In the initial stage doctor may suggest you to use artificial tears for sensitive post-operative eyes in which case you have to use drops more than four times a day. For more precaution you may use preservative-free drops because you may not be got enough treatment from artificial tears.
After LASIK Punctal occlusion can be done to help with developing the extent of time that tears stay on the ocular surface. For a safe, effective and flexible cure you can use Punctal plugs for dry eyes problem. Thermal Punctal occlusion can also consider for those patient with more sustained symptoms, and specifically those who have had development of dry eye signs and symptoms with plugs.
For the treatment of post-LASIK dry eyes patient need to be addressed the quality of tear. It should be identified and treated that ocular surface discomfort and inflammation of the ocular surface which are mainly caused by Meibomian gland dysfunction. In traditional treatment these measures such as warm moist compresses and gentle lid massage or scrubs are included. Few patients are also get recovery by using a course of oral tetracycline, usually doxycycline, which has anti-inflammatory influence on the skin and Meibomian glands.
In the severe cases of dry eyes scleral contact lenses can be a good option of treatment. The patient with post-LASIK dry eyes are getting improvement by using Scleral gas-permeable contact lenses. For a healthy environment for the ocular surface you need supports by the prosthetic replacement of the ocular surface (PROSE). In the diversity of dry eye condition PROSE has been revealed to offerdevelopment in dry eye signs and symptoms.
It is difficult to improve condition and gain optimal surgical outcomes for the patients who are at risk with severe post-LASIK dry eye. Before to surgery, LASIK candidates have need to examine some important components such as the tear meniscus, tear quality, tear break-up time, presence of lid disease, Schirmer testing, and any ocular surface staining. Though there is no unique diagnostic check for dry eyes, there is substantial proof that tear osmolarity testing can offer essential material about dry eye severity and may be of value in identifying patients at risk for post-LASIK dry eye.
