It is very important to maintain the thickness of the cornea.

1. To reduce the risk factor and complications for LASIK surgery.

Many researches done and are proven that prolonged usage of contact lenses for years, will cause the thinning of the corneal thickness. Thus, reducing the number of patients eligible for LASIK. Ectasia or Keratectasia after LASIK (changes can occur after LASIK surgery as early as 1 week or can be delayed after several years after the LASIK surgery) could be a risk factor, too.

2. To prevent corneal warpage.

While wearing the contact lens, cornea thickness could become thicker or thinner. Normally, during adaptation period, cornea will be thicker. And then become thinner throughout prolonged periods of wearing.  Study done by Schornack (2003) showed that individual who wear contact lenses can experience corneal warpage. This include changes in refractive error, decreased visual acuity with spectacle correction, and changes in corneal topography.

3. To diagnose eye pressure accurately.

The Ocular Hypertension Study (OHTS) studies was released in 2002, mainly was to determine if early intervention with pressure lowering medications could reduce the number of ocular hypertensive (OHT) patients that develop glaucoma. However, a critical discovery was made regarding corneal thickness and its role in intraocular eye pressure and glaucoma development. Corneal thickness that varies with each contact lens wearer might cause doctors to diagnose to treat you for a condition that may not really exist or to treat you unnecessarily when are normal. Might be underestimate or overestimate the reading.
