Seawater - Swimming Pools

Important considerations after Lasik, All-Laser Lasik, PRK, LASEK, Epi-Lasik, CK, RLE, and P-IOL

Swimming pools and natural bodies of water contain many contaminants that are dangerous to eyes healing from refractive surgery.

 

Seawater is full of active and inert organisms that would be of no positive value if they were to permeate a cornea compromised by refractive surgery. All refractive surgery techniques including  conventional or wavefront Lasik, All-Laser Lasik, PRK, LASEK, Epi-Lasik, NearVision CK, and RLE will require protection from such contaminated environments for a period of time. Swimming, skiing, scuba diving, surfing, even sailing can all contaminate the eyes. Swimming pools, although chlorinated, can cause problems with eyes healing from refractive surgery too.

PRK, LASEK, and Epi-Lasik disrupt the epithelial layer of the cornea, making it more susceptible to infection. For these types of refractive surgery, staying out of seawater for at least 4 weeks or as otherwise instructed by your doctor would be wise.

Conventional or custom wavefront Lasik and All-Laser Lasik have a flap of corneal tissue that is less disruptive to the epithelium, but creates an interface where foreign particles may lodge. The outer edge of the Lasik flap seals within about 2-3 weeks.

Lens based procedures such as RLE and P-IOL require incisions through the cornea into the eye and are significantly more susceptible to problems than the surface ablation techniques of PRK, LASEK, and Epi-Lasik, or the flap techniques of Lasik and All-Laser Lasik. For this reason, seawater exposure should probably be limited for at least 8-12 weeks.

Although CK uses a probe to enter the cornea, the likelihood of organisms being able to breach this tiny hole after 2 weeks is very small, so waiting about that amount of time would seem reasonable.

In all cases, any sort of postoperative problem may require significantly more time away from seawater or similar environments. Before putting your eyes in anything that is not sterile, consult your doctor.

Wavefront or conventional ablation will make no difference regarding how long one must be out of seawater or chlorinated pools. That means that you need to be out of seawater and pool water just as long if you have wavefront or if you have conventional ablation.

If you are ready to choose a doctor to be evaluated for conventional or custom wavefront Lasik, All-Laser Lasik, PRK, LASEK, Epi-Lasik, NearVision CK, RLE, or any refractive surgery procedure, we highly recommend you consider a doctor who has been evaluated and certified by the USAEyes nonprofit organization.

Theoretical model and design of a device to reduce the influence of environmental factors on refractive surgery outcomes.

Conf Proc IEEE Eng Med Biol Soc. 2006;1:343-6

Authors: Schena E, Silvestri S, Franzesi GT, Cupo G, Carito P, Ghinelli E

Recently many different groups show that environmental temperature and relative humidity affects the outcomes of refractive surgery performed by excimer lasers in an unpredictable fashion. A theoretical model of the water vapor absorption at 193 nm wavelength is presented and discussed in order to quantitatively assess the influence of environmental parameters on the laser energy that actually reaches the corneal surface. Model simulations show that laser energy absorption (up to 7% of the available energy) occurs along the path of laser beam, into the existent space between the laser beam source and the patient's eye, and is caused by environmental temperature and relative humidity (respectively 35 degrees C and 95%). Our findings suggest that this energy loss reduces the ablation rate, producing a significant under-correction of the treated corneas. A cost effective device which keeps thermo hygrometric parameters constant along the laser beam path, is also provided.
