If you are having difficulty in reading then you might be suffering from presbyopia. This fairly common vision disorder usually occurs with advancing years, in the patients’ 40s. Presbyopia is caused by the thickening and hardening of the lens of the eye.
Diagnosing the Need for Surgical Reversal of Presbyopia
Since Presbyopia is an age-related disease, it is nothing to get alarmed about. Try and see if you have all the symptoms and visit an ophthalmologist to decide the best method for surgical reversal of Presbyopia. You might need to go for presbyopia treatments if you:
* can’t read small print
* need to keep the material farther away to read it
* suffer eyestrain in reading
* can’t easily see the contrasts between small bits of texts
* ed increased light while doing reading or other works needing close look at objects
Types of Presbyopia Treatments
There are many Presbyopia treatments through which surgical reversal can be achieved. These include:
* Glasses: The use of corrective eye glasses, particularly progressive or bifocal lenses while reading is a common method of vision correction in this case. Single vision or focus glasses are usually prescribed just for the purpose of reading. These glasses will not help you see things across the room the way bifocals can.
* Contact Lenses: Some people prefer wearing contact lenses instead of corrective eye glasses due to their convenience. Interestingly, more and more people are opting for a ‘monovison’ setup where in one lens has correction for near sight while the other has correction for far sight. With both eyes open, vision is generally clear.
* Surgical Treatment: This is a permanent solution for presbyopia. These days, laser techniques such as Lasik are also used for surgical reversal of presbyopia.
Method of Surgical Reversal of Presbyopia
Lasik is the most common of all presbyopia treatments. In this method an incision is made and a flap is created in the cornea with the help of a surgical blade. Then laser is applied to remove the targeted tissue of the cornea to reshape it. The whole process takes just a few minutes and is quite painless.
If you are worried about your failing eyesight, you can consult the eye specialists at the Laser Eye Center of Silicon Valley. The center has the most modern equipment and one of the best treatment success rates in the state of California.

Glaucoma is a disease that affects the eyes and if not treated can permanently damage the optical nerve which can result in blindness and loss of vision. This article will detail a few Glaucoma therapy treatments available and the advantages and disadvantages regarding each.
The damage caused by glaucoma is commonly caused by a high intra-ocular pressure. This pressure is provided by a clear liquid, aqueous humor, which flows through the eye helps to maintain and nourish the tissue within the eye.
In circumstances where the production of this liquid is increased and the methods for drainage are decreased damage occurs to the nerves and peripheral sight is lost, this effect is called Open Angle Glaucoma (OAG).
A way to treat this form OAG is to assist in lowering the pressure within the eye, the treatment for this is usually through eye drops, laser therapy or surgery.
The most common Glaucoma therapy treatments are the eye drops, the disadvantages for using eye drops are that they can be expensive, messy and can have side effects. In addition to this depending on the severity of the OAG you may need to use them for the remainder of your life. Some of these drops assist in draining the fluid whilst others act to reduce the amount of fluid produced, the effect being the same.
Lasers also can be used for Glaucoma therapy. This technique is called laser therapy. Laser therapy uses lasers to target the cells in the eye which contain melanin which is a natural pigment. The body will then act to repair the damaged cells and as an effect of this will decrease the pressure that has built up within the eye.
Glaucoma as stated can cause permanent loss of vision if it is not treated. There is no way to determine whether the glaucoma has been successfully controlled and as such if you have this condition you should make regular trips to your GP to ensure it does not get out of control.

LASEK surgery is a form of laser eye surgery that corrects refractive errors by reshaping the cornea – to this day, thousands of people the world over have benefited from this revolutionary procedure. LASEK eye surgery is performed on patients whose corneas are either too thin or too flat for LASIK eye surgery, but both procedures offer the same results in vastly improved vision and negate the need for glasses or contact lenses.
Who Can Benefit From LASEK Eye Surgery?
Patients who suffer from refractive errors will be delighted to learn that LASEK eye surgery can once and for all allow them to live life with more freedom and no longer rely on corrective eyewear.
LASEK eye surgery can be used to treat the following refractive errors:
- Short-sightedness (myopia) – This eye condition results from the cornea being slightly rounder and shorter than it should be. Due to this, the light that enters the eye converges just in front of the retina, meaning that suffers experience difficulty when trying to see a clear image at a distance. Through LASEK eye surgery, the shape of the cornea is corrected and the light is made to focus precisely on the retina – meaning that the blurred images at a distance will become a thing of the past, eliminating the effects of short-sightedness!
- Long-sightedness (hyperopia) – Patients who suffer from hyperopia have a cornea that is slightly flatter and shorter than it should be. This results in a blurred image because the light that enters the eye focuses on a point just behind the retina. Most people who suffer from this refractive error rely on glasses on contact lenses, but through LASEK eye surgery, the effects of hyperopia can be permanently corrected. That means no more headaches and straining eyes to get objects – both near and far – into focus.
- Astigmatism – In this case, the cornea is a more conical shape than it should be – this means that light enters at different angles through this cone. This creates two points of focus and ultimately a blurred image. Although this condition is slightly more complex than myopia or hyperopia, using the right technology, virtually all astigmatism symptoms can be treated through LASEK eye surgery.
What Does the LASEK Procedure Involve?
A patient is deemed an appropriate candidate for LASEK eye surgery when they suffer from one of the above mentioned refractive errors and usually because their cornea is not thick enough to withstand LASIK eye surgery. During the LASEK procedure, an ophthalmic surgeon focuses of the preservation of the corneal epithelium. In this way, the procedure differs from both LASIK and as the surgeon does not create a corneal flap or scrape and remove the epithelium.
LASEK treats the epithelium with a diluted alcohol solution which loosens it; the surgeon then rolls the epithelium tissue back and works with a laser to reshape the exposed corneal tissue beneath. The surgeon then simply smoothly rolls back the epithelium cells in their new reshaped position.
What Happens After Laser Eye Surgery?
Recovery time from LASEK eye surgery tends to take slightly longer than that of LASIK, but in the hands of expert surgeons, the visual outcomes are the same. Patients experience vast vision improvement with maximum convenience.
Post-treatment, patients are usually prescribed medicated eye drops which aid the healing process and relieve any temporary discomfort during this time. For about the first week, patients are given a night shield to wear when sleeping, which prevents any accidental rubbing of the eyes. In some cases, patients are fitted with soft contact lenses to give further protection to the healing eyes.
Patients who undergo LASEK eye surgery will find they have a newfound freedom as they no longer have to rely on glasses or the deal with the hassles of contact lenses or spectacles. Due to their vast visual improvement, many patients say that their self-esteem is boosted, along with their confidence!
The London Vision Clinic is leading laser eye surgery clinic in the UK, boasting world-class ophthalmic surgeons who expertly perform LASIK and LASEK eye surgery.

Thinking about eye surgery using a Lasik procedure is a big step, and many people are a little hesitant to ask the questions that they have. The Lasik procedure, though widely talked about, is not discussed in detail, and people tend to fear the unknown. This article addresses some of the more commonly held fears, and talks about the experience for the vast majority of people that undergo a Lasik procedure.
One of the most common fear, both when it comes to the Lasik surgery and any operation in general is the fear of pain during and after the surgery. When a Lasik surgery is performed the eye is applied with numbing drops. The patient also receives a mild sedative so they can relax and feel comfortable. So even though you may feel a minor pressure to the eye, it is relatively pain free
The surgeon does use a laser in the eye to help reshape the cornea during the Lasik procedure. Many folks are worried about the laser being shone directly into the eye, or that they might look away and, due to this, develop a serious complication with their eyes and the Lasik laser beam effects. In actuality, the laser is only active for ten to fifteen seconds for each eye, and the Lasik machine has a tracking system that allows the beam to be on only when the eye is in the correct position.
Another general fear for people contemplating a medical procedure is fear of “the scalpel”. Any Lasik procedure uses only a very small microkeratome blade to approach the eye, or some more recent Lasik innovations have the laser itself created the flap and avoid using any hard surface at all. There is no reason to be concerned about a scalpel, for the Lasik physician does not use one.
Many wonder about the horror stories they hear about this or any other operation, and wonder about serious consequences like going blind. According the government statistics taken by the FDA, there are no reported cases of blindness due to a Lasik operation.
Actually, the risk of a serious permanent complication due to the Lasik procedure is less than 1 percent, and the risk of any permanent complications even if not serious (such as light halos) is 3 percent or less. It is extremely rare for a patient to not have improved vision after a Lasik procedure.
If the fact that you are awake and your eyes are open during the operation bothers you, just remember that you are given a mild sedative and your eyes will be dripped with numbing drops.
Is it more the thought about the Lasik physician’s hand close to the eye that bothers you? Then just think about that your eyes will be applied with drops that make your vision black out for the ten to fifteen seconds the operation takes.
