- Cataract is considered one of the main causes of poor eyesight in the whole world, and cataract constitutes 75% of the causes of blindness, while other diseases (glaucoma – corneal opacity – retinal detachment – eye bleeding … etc) constitute 25% of the other causes.
- Cataract is an opacity in the crystalline lens of the eye which prevents the light from entering the eye.
- The natural eye lens is transparent, so the pupil appears black, but in the case of advanced cataract or lens opacity, the pupil of the human eye appears gray or opaque.
- Cataract is an opacity that affects the natural lens of the eye and leads to a decrease in visual acuity and a lack of clarity in vision, however in most cases vision is fully restored after removing the cataract surgically and inplanting a transparent lens in it place, especially if there’s no eye disease that affects vision.
Causes of cataract
- There are many causes of cataract from exposure to chemicals, drugs, radiation, or exposure to trauma in the head area, and there are also genetic causes, and the simplest and most common factor is the age factor, and as mentioned above, cataracts are nothing but the lens of the eye after it has become opaque.
- The cause is also due to old age, followed by diabetes, then glaucoma, then chronic eye infections or violent trauma of the eye or head, and finally congenital cataract.
Symptoms of cataract
- Cataract begins with mild symptoms of blurry vision and lack of clear vision even with frequent renewal of glasses, and sometimes this vision impairment may be more annoying in high light degrees and during going out in the sun, and sometimes the opposite, depending on where the opacity is in the lens of the eye, and with time the opacity increases To affect vision to a degree that may hinder normal vision completely
- When the degree of cataract reaches a degree that obstructs vision to the point of disrupting normal activities, it must be removed, and in recent years this is done by surgery or ultrasound through a very small opening, or by a femto-laser, where the surgical scalpel is not used at all with the implantation of a soft lens. Through this small aperture, and there are multiple options for this lens, including monofocal, multifocal and astigmatic lenses.
- Cataract is treated surgically or by means of ultrasound waves or femto-laser only. There is no chance for medical treatment at all, but surgery is the only solution to remove the cataract from the eye and replace the opaque lens by an artificial transparent foldable lens.
- The surgery is simple and fast and does not take more than 10 minutes in the operating room, and after that the patient is discharged with an eye patch that is removed after 6 hours, and then the patient practices his activities in a normal way of seeing, working and interacting with life .
- The success rate of cataract surgery is 98 %, Making it the most successful and best eye surgery.
