Dry Eyes After Lasik and Bladeless Lasik

Dry eye prevention techniques to use with Lasik, Bladeless Lasik,
PRK, LASEK, and Epi-Lasik.

Lasik and Bladeless Lasik may induce dry eye symptoms during the normal six month healing period.  

Dry Eyes after Lasik is a common condition during the immediate recovery period. If you have dry eyes before conventional or custom wavefront Lasik, Bladeless Lasik, PRK, LASEK, or Epi-Lasik, you may not be excluded as a candidate for refractive surgery, but it is a condition that you must report to your doctor. Pre-existing dry eyes needs to be evaluated, treated, and resolved before surgery.

This article is about why dry eyes occur and how to prepare before surgery. A related article is  Lasik dry eye treatment.

Tear Quantity, Tear Quality

Two popular methods to test for dry eyes is a Tear Break-Up Test (TBUT) to determine tear quality and a Schirmer test to determine tear quantity. Dry eye treatment will depend upon the cause and severity of the dry eyes. Dry eyes is a medical condition and treatment would normally be covered under by major medical insurance plans.

Lasik Induced Temporary Dry Eyes

It is common to experience dry eyes for a short period after Lasik, Bladeless Lasik and sometimes PRK and its cousins LASEK and Epi-Lasik. Virtually everyone who has Lasik or Bladeless Lasik will experience dry eyes, but the important issue is to what degree and for how long.

For the vast majority of refractive surgery recipients, the degree of dry eye symptoms is not significant enough to cause difficulties. Even those who do have some trouble most often find the dry eye symptoms resolve within the normal six-month healing period. For an unfortunate few patients, Lasik induced dry eyes is a long-term complication that, although manageable, may be very disruptive.

There are many techniques to reduce the probability of dry eyes being induced by surgery, but most are the responsibility of the doctor. Prevention of Lasik related dry eyes is primarily focused on proper patient selection and treatment of pre-existing dry eye prior to surgery.

Drowning In Artificial Tears

There are many techniques to treat dry eye. The most common are preservative-free artificial tears, lubricating gel, punctal plugs, Restasis, and flax seed oil supplements. The technique best suited depends upon the exact nature of the tear deficiency and underlying cause. There are many types of artificial tear eye drops for slightly different purposes.

Less Dry Eye With Surface Ablation

Although PRK, LASEK, and Epi-Lasik may induce dry eye symptoms, Lasik and Bladeless Lasik seem to be the more commonly associated with dry eyes. This is partly because the Lasik techniques are more disruptive to the corneal nerves than PRK and LASEK. For this reason, patients with preexisting dry eyes may find PRK, LASEK, or Epi-Lasik a better choice. Other techniques such as RLE, and P-IOLs only marginally disrupt the corneal nerves, but have their own limitations. Whatever the surgery of choice, the less the corneal nerves are disrupted, the faster the nerves recover and normal tear function returns.

Be sure to discuss any dry eye problems (before or after surgery) with your doctor.

[Comparison of corneal nerve regeneration and dry eye condition after conventional LASIK and femtosecond-assisted LASIK].

Zhonghua Yan Ke Za Zhi. 2015 Mar;51(3):188-192

Authors: Yu C, Li Y, Wang Z, Jiang Y, Jin Y

OBJECTIVE: To compare the regeneration of subbasal epithelial nerve plexus in the central cornea and dry eye condition between patients undergoing conventional LASIK surgery and femtosecond-assisted LASIK surgery.
METHODS: It was across-sectional study. Thirty patients (60 eyes) who had LASIK at our hospital from October 2011 to September 2012 were included in this study. Patients were divided into conventional LASIK group and femtosecond-assisted LASIK group based on the method used for corneal flap creation. Subjective and objective dry eye tests were carried out at 1 year after surgery. HRT III confocal microscopy was used to observe the regeneration of subbasal epithelial nerve plexus,and the images were analyzed by ACCMetrics software using quantitative parameters to determine the density and morphology of corneal nerve fibers. The data of corneal nerve fibers and dry eye condition in the two groups undergoing different LASIK procedures was compared using an independent sample t test.
RESULTS: During the one-year postoperative follow-up, the Schirmer test result, tear film break-up time value, and ocular surface disease index score in the F-LASIK group [(12.65±8.73) mm/5min, (7.85±2.81) s, (7.25±6.35) points] were not significantly different from that in the C-LASIK group [(16.73±10.55) mm/5min, (8.77±3.04) s, (4.46±5.37) points] (t=1.399, -1.050, -1.613, P>0.05). Regarding the nerve fiber measurements, which included corneal nerve fiber density, corneal nerve branch density, corneal nerve fiber length, corneal total branch node, corneal nerve fiber width, and corneal nerve fiber tortuosit, there was no statistically significant difference in their results between patients who had femtosecond-assisted LASIK surgery [(16.46±6.65) /mm(2), (19.27±9.56) /mm(2), (10.88±4.70) mm/mm(2), (65.10±38.43) /mm(2), (4.76±0.34) µm, (2.30±0.34) grades] and those who had conventional LASIK surgery [(15.99±7.14) /mm(2), (19.39±7.07) /mm(2), (11.30±3.17) mm/mm(2), (68.43±34.94) /mm(2), (4.73±0.24) µm, (2.14±0.34) grades] (t=-0.229, 0.049, 0.365, 0.306, -0.394, -1.629, P>0.05).
CONCLUSION: The difference between conventional LASIK and femtosecond-assisted LASIK does not significantly affect the dry eye test values and nerve fiber measurements in patients at 1 year after LASIK. (Chin J Ophthalmol, 2015, 51: 188-192).
