Cataract and hyperopia (farsightedness)
Quite often cataract (partial or full dimness of the crystalline lens) is combined with age-related farsightedness (presbiopia). Both of these disorders often develop after the age of 40-45 even in people who has had good vision throughout their life. These two disorders differ in their development mechanism. Even when the cataract has been successfully treated, there still remains presbyopia which means wearing glasses to have vision at close distances.![farsightedness]( "farsightedness")
One operation does away with cataract and presbyopia
Nowadays, it is ultrasonic phacoemulsification with the implantation of an artificial multifocal lens that resolves the problem of poor vision and does away with cataract and hyperopia simultaneously. with the implantation of an artificial multifocal lens that resolves the problem of poor vision and does away with cataract and hyperopia simultaneously. This operation takes 15-20 minutes and is performed with local drop anesthetic on an out-patient basis. The surgeon performs all the manipulations through a self-sealing micro-incision of 2.5 mm. This surgery does not require suturing. A special feature of the operation is that a multifocal lens is implanted into the eye.
Intra-ocular lenses
The multifocal intra-ocular lens (artificial crystalline lens) has a special structure of the optical section which imitates the function of a natural crystalline lens. The multifocal lens possesses more than one focus and this ensures good vision of objects at different distances. After this implantation, the patient can read, write, and work with small objects without wearing glasses or contact lenses.
According to clinical observations, 85% of the patients who had multifocal lens implanted no longer use glasses.
