Cataract & Corneal Refractive Subspecialist
Lawrence C. Chao, M.D.
Cornea | Comprehensive Care
The cornea is the clear curved window of the eye which is responsible for providing two thirds of the light bending ability of the entire eye.
It is crucial that the cornea remains healthy and clear for good vision.
Several diseases and conditions can compromise the structure and function of the cornea. Medical strategies to obtain good vision are always tried first, but if these are not successful in providing good vision, corneal surgery is often needed.
As a fellowship-trained cataract, cornea and refractive subspecialist, Dr. Chao's extensive experience allows him to manage routine as well as complex cornea cases. Specializing in LASIK, ICLs, cataract, cornea, and refractive vision correction, Dr. Chao provides consults and second opinions at Chao Vision Institute in Irvine, Orange County, CA.
Dry Eye Syndrome | K Sicca
Keratoconjunctivitis sicca or K Sicca, also called keratitis sicca, sicca syndrome, xerophthalmia, dry eye syndrome, dysfunctional tear syndrome, or simply dry eyes, is an eye disease caused by decreased tear production or increased tear film evaporation commonly found in humans and some animals.
With dry eye syndrome, the eye doesn't produce enough tears, or the tears have an abnormal composition. It may be caused by abnormal eye anatomy, systemic inflammatory diseases, environmental and occupational factors and/or as a side effect of medication.
When there is a chronic lack of sufficient lubrication and moisture, the eyes become red and irritated, causing a feeling of burning and scratchiness. Often, dry eye syndrome makes it difficult to wear contact lenses and patients seek to get LASIK. If dry eye is a preoperative condition, we recommend treatment of the dry eye condition be started prior to proceeding with refractive surgery. Today's over-the-counter as well as prescription eye drops, and plugs offer relief for treatment of K sicca.
Cornea Transplantation | Penetrating Keratoplasty (PKP)
Corneal transplantation, otherwise known as Penetrating Keratoplasty (PKP), is a surgical procedure to replace a damaged or diseased cornea with donated human corneal tissue.
Corneal tissue is received from a deceased human donor and tested to be free of disease or injury. Sutures secure the donor cornea in place for approximately one year. There are significant risks and benefits to this operation which should be discussed with your surgeon prior to considering this surgery.
Descemet Stripping Automated Endothelial Keratoplasty (DSAEK)
The cornea is composed of five layers, all together measuring about half a millimeter in thickness centrally. The epithelial layer of the cornea regenerates quickly while the innermost endothelial layer cannot regenerate.
Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) is a relatively new procedure in which the inner cell layer of the cornea is selectively removed and transplanted.
Again donated human corneal tissue is utilized. This lamellar or layered corneal transplant offers a less invasive surgical solution for those diseases that selectively affect the innermost portion of the cornea. Healing and visual recovery is generally quicker for this partial layered procedure compared to PKP cornea transplantation.
Eye Health | Ophthalmology News & Education
Grow "longer, darker, fuller lashes" seems to be the latest health and beauty trend. As the first FDA-approved lash-growing product, Latisse™ (bimatoprost ophthalmic solution, Allergan) 0.03% is available by prescription only.
Indicated and used to treat hypotrichosis of the eyelashes by increasing their growth including length, thickness and darkness, the manufacturer of Latisse™ warns in its package insert that pigmentation of the eyelids and iris may occur. While the darkening of the eyelids may be reversed with discontinuation of use, darkening of the iris is likely to be permanent.
Before using Latisse™ or any lash or lid products that may affect your eyes and/or vision, consult an ophthalmologist.
