Cataract refers to a visually impaired disease caused by decreased transparency or color change of the lens. Its pathogenesis is more complicated, and it is the result of the long-term comprehensive effect of internal and external factors on the lens. It is more common in people over 50, mainly manifested as decreased vision, blurred vision, and double images.

 

Early Symptoms of Cataract

 

The early symptoms of cataracts are like a haze in front of the eyes, blurred vision, changes in vision, continuous decline in vision, and life activities are affected. If you do not go to the doctor or treatment for a long time, cataracts will bring many complications, such as glaucoma, the optic nerve will also be affected, and serious or even permanent blindness.

 

Because everyone has different individual differences and different requirements for eye use, there is no hard and fast standard for the timing of surgery. Generally, as long as cataract has affected daily work activities, surgery should be performed as soon as possible.

 

The Necessity of Cataract Surgery

 

The following aspects can help you determine whether you are ready for cataract surgery.

 

Cataracts can affect your daily or professional activities. Cataracts can affect the ability to drive safely at night. Cataracts also increase the sensitivity to glare, which is a big trouble for those who like outdoor activities. Use some simple tools to delay cataract surgery, such as polarized sunglasses and wide-brimmed hats to reduce glare, and a magnifying glass helps you read easier.

Cataract is the result of lens aging, and its essence is protein denaturation. As far as the current level of medical development is concerned, there is no medicine that can prevent or reverse this process. Surgery is an effective way to treat cataracts. Therefore, cataracts should be operated as soon as possible, and the treatment effect will be better.

 

In recent years, as the needs of patients have changed, cataracts have developed rapidly in terms of surgical techniques, ophthalmic instrument set, equipment used in ophthalmology, and intraocular lenses. At present, the mainstream is small incision cataract extraction and intraocular lens implantation, and another more advanced is phacoemulsification and intraocular lens implantation. It is generally recommended to perform phacoemulsification and cataract implantation. This kind of operation has small trauma and quick recovery and short healing period. This type of operation is recommended.

Instruments Needed for Cataract Surgery

 

Cataract surgery is a very common operation in ophthalmology, and the instruments it needs are microscopic instruments commonly used in ophthalmology. Generally, the following equipment is required: the operation should be performed under a microscope, and an operating microscope and ophthalmic speculum are required. Phacoemulsification surgery for cataracts requires a phacoemulsifier. In addition, there are fiber instruments used in surgery, such as eye cannulas surgical instruments, micro tweezers, mini medical scissors, disposable surgical scissors, needle holder with suture scissors, puncture knives, tunnel knives, triangular knives, and crystal positioning hooks.

 

Capsulotomy forceps, corneal trephine blade and lens insertion forceps are professional instruments for eye surgery, which are different from other surgeries. Use surgical instrument cleaning solution to sterilize the micro-surgical equipment to prepare for surgery.
