Eye Surgery Products

Although most eye surgery products are considered safe, a few come with risks that potential patients must be made aware. All systems and products were created and designed by human knowledge, so they are not perfect. Perfection can be reached only through Jesus Christ."If by any means I might attain unto the resurrection of the dead. Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus. Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before, I press toward the mark for the prize of the high calling of God in Christ Jesus. Let us therefore, as many as be perfect, be thus minded: and if in anything ye be otherwise minded, God shall reveal even this unto you." (Philippians 3: 11-15)

Surgical devices come in several forms. Phacoemulsification and laser correction are both systems designed to improve the surgical process and a patients vision while minimizing risks. Viscosurgical Devices, also referred to as OVDs, are thick liquid like substances used to keep the eye from collapsing during surgery. Intraocular lenses are part of the group of products designed to permanently correct nearsightedness. Despite being useful and convenient for the patient, these types of lenses have serious risks involved with their use. There is a group of high-tech eye surgery products called excimer lasers. One other product that will be discussed in this article is an instrument called a microkeratome. The microkeratome is one of the few devices that actually include a blade. Simply put, the oscillating blade separates the surface layers of the cornea during Laser-Assisted in situ Keratomileusis (LASIK).

During surgery, a microkeratome is placed over the eye and held in place with suction. A small hinged flap is created by the instrument. Then a surgeon uses a laser to sculpt the cornea under the flap into a desired shape. LASIK is now a common procedure, but, despite development of safer and more reliable eye surgery products and tools, the operation does have a few possible risks of complications. Keep in mind, nothing is completely safe and without risks. According to a surgery website, LASIK involves creating the small thin surgical flap. During the LASIK procedure, the surgeon lifts the surface flap and then uses laser energy to reshape the cornea. Once this is done, the flap is replaced. Unfortunately, there are at least two possible risks with creating a flap during surgery. First, the flap could be damaged or come off completely. Second, improper healing of the flap could distort the cornea. However, there are other complications that could arise during and after any corrective vision surgery.

Fortunately, technology has produced several eye surgery products designed to reduce risks and increase patient discomfort during and after the procedure. The slit scanning laser uses small beams that are linked to a rotating device with slit holes. During surgery, the beams scan across these holes and removes surface cells. The advantage of this type of laser is a uniform beam and a smooth ablation area. But slit scanning lasers also have a greater risk of overcorrection not associated with other devices. Spot scanning lasers are the most common type. Basically, spot scanning uses small beams to produce the ablation zone. This type of laser is thought to produce the smoothest ablations while treating astigmatism. Wavefront-quided lasers use light waves to detect and record ocular defects. Spot scanning and slit scanning lasers are both compatible with wavefront-guided systems and are valuable eye surgery products.

During some types of procedures, a technique called phacoemulsification is used. The operation is complicated and uses a variety of eye surgery products. First, the surgeon makes a small incision at the edge of the cornea. He or she then makes an opening in the membrane that surrounds the cataract lens. An ultrasonic device breaks up the cloudy lens into fragments. These fragments get suctioned out of the capsule. The capsule will provide room for and support an intraocular lens (IOL). Intraocular lenses are implanted permanently into the eye. IOLs reduce the need for glasses or contact lenses by causing light entering into the eye to be heavily concentrated on the retina. Intraocular lenses are made of either plastic or silicone. Unfortunately, the list of potential risks for this category of eye surgery products is lengthy. Keep in mind, most are rare. First, a person could lose his or her vision. If problems occur, additional surgery could be needed to remove, replace, or reposition the lens. Optimal vision is not guaranteed with IOL devices. Retinal detachment, pressure, and a cloudy cornea are possible developments. Bleeding, inflammation, and infection could lead to permanent loss of vision or even of the eye itself.

During the phacoemulsification process, liquids are lost, which requires the use of other eye surgery products called ophthalmic viscosurgical devices. The capsule that will eventually contain the IOL is at risk of collapsing, so two types of ophthalmic viscosurgical devices are commonly used: dispersive and cohesive. Dispersive viscoelastics are thick. In fact, one online source describes them as having the consistency of molasses. The characteristics of dispersive viscoelastics make them suitable for coating the eye structures, and they don't wash away easily during the operation. On the other hand, cohesive viscoelastics are thicker and don't flow well. The benefit of the cohesive OVD is that it pressurizes and maintains the structure of the eye. Surgeons must carefully remove all traces of the OVDs from the eye or complications could develop later on.

Eye Care Products

There are a number of eye care products on the market that provide moisture, healing, and vision protection for weak sight. Eye care is something that people don't really even think about until it affects them. Each person gets one pair of eyes to last a lifetime. Most people ignore their eyes unless they feel pain, irritation, or have vision problems. Eyes are very complex sensory organs. Approximately 85% of everything an individual's brain thinks about comes from what a person sees. Touch, smell, taste, and hearing combined constitute the remaining 15%. That is why eye health is so critical. As people age, there is usually a diminished capacity to see. Conditions that cause a person's sight to become more limited and numerous and varied. Suffice it to say that, overall health conditions play a huge role in vision. Many diseases that afflict the body also wreak havoc on a person's eyes. There are a number of eye care products on the market that can help. People often must depend on aids such as glasses or contact lenses to clearly read or experience what is around them. The structure of the eyes is meant to optimize vision under various lighting conditions. People have a certain capacity in the daylight. In many cases, people who need glasses to read while indoors, can often see perfectly clearly when they are out of doors in direct sunlight. Protecting a person's vision is one of those things most people take for granted until it's gone.

Regular computer users often experience eye strain. Over 50% of daily computer users observe headaches or blurred vision along with symptoms of strain. Lubricating drops can provide a quick short term solution. There is a caution in using these relieving drops. If, in fact, the drops contain preservatives, doctors suggests that a person use them sparingly. However, for those drops without preservatives, frequent use of these types of eye care products are encouraged. Eye drops have been long available over-the-counter. Though used for some very powerful treatments, some of these drops are marketed as artificial tears; just plain lubricants. The main purpose of artificial tears is to prevent and relieve dry eyes. Eyes usually dry out when a person doesn't blink for long periods of time. Research has shown that people who spend many hours at the computer; will often forget to blink. As a result, the eyes become tired and dried out. Eye drops are usually composed of a saline solution combined with a specific medication for the eyes. Eye care products have been available for over thousands of years. The dropper method is simply an easy way to administer the medication. Often steroids, antihistamines, and non-steroidal anti-inflammatory drugs are used in drop form according to the condition being treated. Glaucoma, post heart attack, and high blood pressure medicines have been developed to used this method of administration.

In addition to treatments that go directly into the eyes, there are eye care products that are taken internally. Dietary supplements are becoming more popular as research has shown the benefits of certain vitamins, minerals, and phytochemicals have been shown to reduced risk of some major conditions and support healthy vision. High doses of vitamin C, beta-carotene, vitamin E, and zinc, in combination has been shown to lower some risks associated with Age-Related Eye Disease. While people of all ages may experience sight problems, more often than not, as a person ages risks are increased for developing conditions that may lead to blindness. Therefore, using eye care products that support healthy vision and reduce these risks, is critical. If a person decides to take a dietary supplement, verifying that the expiration date has not passed on the product, is critical in that freshness is important to the potency of these types of products.

Additionally, researchers found that utilizing capsules instead of hard tablets, both improved absorption rate, and was more easily tolerated in the stomach. As with most prepared food and nutritional substances, organic ingredients are best. Organics ingredients are grown without the pesticides and steroids that are so common in farming processes. Although organic may be more expensive, the benefits far outweigh the costs in both the long and short run. A person wouldn't think twice about putting premium gas into their car, if recommended by the car manufacturer; however most people do think twice about using only the best eye care products. Because eyes are so important to everything a person does, this would not be the time to skimp on quality. If a person has allergies, the dairy products, corn, or wheat that are often used as fillers in these products, could have an adverse impact. Most reputable dietary supplement producers will create formularies that don't contain these types of ingredients. "So that servant came, and shewed his lord these things. Then the master of the house being angry said to his servant, Go out quickly into the streets and lanes of the city, and bring in hither the poor, and the maimed, and the halt, and the blind." (Luke 14:21)

Goggles have also been developed that deliver moist heat and help prevent tear evaporation. Heat packs and eye cushions have also been used to relieve styes. Whether a person decides to use eye care products for prevention or treatment of an existing condition, one thing is for sure, eye care is extremely important. There is only so much a person can do to protect and keep their eyes healthy. Having an examination at least once a year with help to find any developing conditions. Waiting until something happens with a person's sight is not the best to have an individual's eyes examined. If a person already has risk factor, more frequent visits to a specialist may be necessary. Blindness is no joke and in most cases, it's irreversible.
