Treatments of cataracts will depend on many factors such as age,daily activities,severity of symptoms,progression of the cataract and if there are other conditions associated with cataracts.
1- In early cataract glasses can treat blurring of vision and sometimes glare with the use of anti-glare coating. Cataract can progress slowly so patient can use glasses for long time or the cataract can progress fast in which the glasses will not be enough to treat it or overcome it. In this case the glasses will improve vision but not to 20 20 vision and the patient is not happy with his or her vision, so the nest option is surgery.
2- Cataract surgery is usually an elective surgery and the patient is the one who will determine if he or she needs to undergo surgery or not. As we said before some people will have difficulty in vision even with small amount of cataract because it will interfere with their daily activities and with there work while other will complain of blurring of vision but he still not interested in cataract surgery because his vision does not affect his daily work like old people.
In the past and before the new Phacoemulsification was discovered, most of the surgeon preferred to wait until the cataract is full matured because it will be easier for them and with less complications to remove the cataract by extracapsular cataract extraction or ECCE, while these days with Phacoemulsification, it will be much easier and with lesser complications to remove the cataract when it is soft.
The most common treatment of cataracts these days is phacoemulsification.
3- Femtosecond cataract surgery treatment or cataract laser surgery is a new way in treatment of cataracts by using femtosecond laser.
4- A new anti cataract eye drops called N-acetylcarnosine shows a promising effects in prevention and treatments of cataracts especially senile cataract.
5- Sometimes cataract surgery can be an emergency one. Large cataract can cause angle closure glaucoma and in this case the treatment will be anti-glaucoma medications and cataract surgery. Dislocated lens can also cause angle closure glaucoma and the treatment will be cataract surgery.
6- Sometimes cataract surgery is indicated when the cataract is so dense. In this case, your eye doctor will find some difficulties to examine your fundus. Although you may not interested in cataract surgery in this point but this cataract should be removed to allow your doctor to view your retina and also to treat it by laser in case of diabetic retinopathy.
7- In case you have cataract in both eyes, the time between both eyes to undergo surgery is between 4 to 8 weeks in case the cataract surgery was uneventful in the first eye.
8- If your condition is pure cataract with no other conditions that affect your vision, your vision after cataract surgery will improve to 20 20 vision in case of uneventful surgery. Sometimes due to co-existence of other ocular conditions like AMD, glaucoma and diabetic retinopathy, your final vision will depend on the damages that caused by these diseases.
