Causes Droopy Eyelids

Dermatochalasis is a disorder of the eyelids characterized by redundant, thin and flaccid eyelid skin and muscle.  Dermatochalasis and the resultant droopy eyelid is a result of the aging process and is much more common in elderly people although dermatochalasis does appear in younger people as well.  It is usually first noticed in the 40’s and then continues to worsen.  Dermatochalasis occurs with equal frequency in males and females and in all races.

Xanthelasma are Lipid Deposits on the Eyelid

Xanthelasma are Benign but

are Cosmetically Unattractive

Xanthelasma are deposits of cholesterol and lipids under the skin’s surface in the eyelid area characterized by yellowish-brown distinct areas that are soft and flat and elliptical in shape.  A xanthelasma usually ranges in size from 5-30 mm in length.  The lesions are symmetrical and bilateral (around both eyes) and tend to increase in number and size.  Xanthelasma are permanent and are benign lesions that usually have no symptoms but are cosmetically unappealing.  They typically appear after the age of 40 but are sometimes apparent even in teenagers.  They usually occur in the inner canthus area (on the eyelids, upper and lower, nearest the nose).

The yellowish plaques represent lipids and cholesterol under the skin.  These may be hereditary but in about 50-60% of patients there is high cholesterol and/or other lipids such as triglycerides.

Cataract Surgery

Using Femtosecond Lasers

Contrary to the belief of many, cataract surgery is not performed using lasers………not yet anyway! In February 2010 the first laser cataract surgery was performed in the U.S. This exciting new breakthrough was performed using the LenSx femtosecond laser now owned by Alcon Labs, Inc. (Ft.Worth, Texas). The technology was developed by the same group that developed all-laser LASIK. Several other companies also have similar technology in the development pipeline. It is important to note that the LensSx technology is FDA approved in the U.S. for three clinical indications but that its availability in the marketplace is extremely limited currently since it only recently received the FDA approvals.

Current cataract surgery is certainly improved over the results from 30-40 years ago but does not deliver the safety and accuracy found in laser refractive eye surgery such as LASIK or PRK. About 35% of cataract surgery patients experience mild to moderate complications (posterior capsule opacification, cystoid macular edema (CME), vitreous loss or endothelial cell loss). Two percent of cataract patients have more serious complications (i.e. retinal detachment, persistent CME, corneal compliations, infection). However, LASIK only has a 0.2% serious complication rate. Therefore, current cataract surgery has a 10 X higher rate of complications compared to LASIK.

Herpes Zoster Ophthalmicus (Shingles in the Eye)

Herpes Zoster (Shingles) Can Cause Severe Problems when it Causes the Eye to be Infected

Herpes zoster ophthalmicus is an infection of the eye caused by varicella zoster virus. Herpes zoster ophthalmicus is the ocular involvement of an overall infection termed herpes zoster, commonly called shingles.  Varicella zoster is the same virus that causes chicken pox.  Once people are infected with this virus, usually by chicken pox as a child,  it remains within the body in a dormant stage in the sensory ganglion (nerve roots).  It is estimated that 95% of all adults harbor this virus and are therefore at risk for shingles.  The risk of obtaining a herpes zoster infection during one’s lifetime is estimated at 10-20%.  Estimates are that in the U.S. alone each year there are one million cases of herpes zoster.

Reactivation of the Varicella Zoster Virus causes Shingles (Herpes Zoster)

The varicella zoster virus can remain in the dormant stage forever or for decades but can be reactivated in some people.  Reactivation of the virus is caused by a decreased immune system that can be caused by aging, HIV, high stress levels or illness.  When  the virus reactivates it usually spreads to the skin causing a severe rash called herpes zoster (shingles).  If the varicella zoster virus spreads down the first division of the trigeminal nerve it is called herpes zoster ophthalmicus.  If the forehead or nose becomes infected, the eye often becomes infected on the same side as the skin involvement.  The incidence of ocular involvement of all shingles cases is estimated to be as high as 25%.

Crystalens AO 

Premium Refractive Lens Implant

Bausch & Lomb has recently introduced their newest intraocular lens implant (IOL), the Crystalens® Aspheric Optic lens.  The Crystalens® AO is the newest addition to the Crystalens line of IOL's.  Crystalens is a premium refractive IOL that functions like a person's own accommodation.  The other lenses are the Crystalens HD and Crystalens Five-o.  The Crystalens family of lenses are the only FDA approved accommodating IOL's.

The Crystalens AO has prolate aspheric surfaces which minimizes or eliminates spherical aberration thereby providing a better quality of image for both distance and near vision compared to spherical IOL's.  The Crystalens AO has zero spherical aberration so it also improves the depth of field.  Unlike some "multifocal" IOL's, vision is unaffected by pupil size in this new lens.

Thin Corneas are a Major Risk Factor for Glaucoma

A major national study called the Ocular Hypertension and Treatment Study (OHTS) proved that the thickness of the cornea is one of the most powerful predictors for the development of glaucomaEyes with a corneal thickness of 555 microns or less (thinner corneas) had a 300% greater risk of developing glaucoma than those eyes with a corneal thickness of 588 microns or more.
