Artificial Tear Eye Drops After Lasik

The selection of artificial tear eye drops required after Lasik, Bladeless Lasik, PRK, LASEK, or Epi-Lasik s very important.

The choice of artifical tear after Lasik is very important.  
   

Every artificial tear manufacturer has a slightly different formula for each brand. Some eye drops are thick to provide more protection, others are thin to provide rapid relief without vision disruption, however all can be divided into one of three categories: preserved, preservative free, preservative free on contact.

The preservatives used in artificial tears are a mild toxin. A purpose of a toxin in an artificial tear is to kill anything that may promote spoilage of the eye drops and to keep the eye drops aseptic.

The eye does not like toxins too much, even low level toxins. Toxins in eye drops can cause irritation, redness, even inflammation. An eye healing from conventional or custom wavefront Lasik, Bladeless Lasik, PRK, LASEK, Epi-Lasik, RLE, or any refractive surgery procedure, needs all the help it can get and applying a toxin is not helpful. Even if the eye drops do not cause irritation and feel fine, the toxins may be slowing or negatively affecting the healing process.

Newer "preservative free on contact" artificial tears have an advantage that the toxin quickly dissipates, but the speed at which the toxin dissipates varies greatly. As an example, one such drop dissipates the preservative by exposure to ambient light. If you put in the drops, close your eyes, and go to bed with the lights out, that preservative is not going to dissipate very quickly. Artificial tears that claim to be preservative free on contact are not necessarily appropriate immediately after surgery.

It is always best to use true preservative free eye drops during the immediate recovery period after Lasik or similar laser eye surgery. It is even a good idea to use preservative free eye drops long after surgery, but they are more expensive and after the cornea has healed adequately an artificial tear with a preservative or is preservative free on contact may be appropriate. Check with your doctor.

If eye irritation is experiences with the use of a preservative free artificial tear, it may be the formulation is incompatible. It is possible that something in a particular formula of a particular brand is causing irritation, with or without a preservative. You would need to try different brands to see what works best for you. Listed below are several of the major artificial tears categorized by active ingredients.

Serum eye drop preparation in Australia: Current manufacturing practice.

Abstract
Serum eye drops are used to treat diseases such as dry eye syndrome (keratoconjunctivitis sicca), a disease of the surface of the eye that results in an unstable tear film. Patients are referred to the Australian Red Cross Blood Service by ophthalmologists for autologous serum eye drops when other therapies such as artificial tears or topical immunosuppressive agents have failed. In order to manufacture autologous serum eye drops, whole blood is collected from the patients using standard blood collection procedures. The blood is then allowed to clot to produce serum and processed into 20% serum eye drops, which are then returned to the patient for their own use. The eye drops are packaged into a long length of tubing, which is then heat-sealed to produce single-use segments. The demand for serum eye drops in Australia is increasing every year, with a 30% increase in the past 12 months.
