Cataract is a clouding of the lens and the leading cause of blindness in the world. Cataract is a multifactorial disease with numerous risk factors, but as the most important cause is considered to be older age. Aging entails various changes within the lens of the eye that contribute to its blur. Symptoms begin with a progressive, painless drop in sight, and in many cases, it is myopisation, reduced contrast sensitivity and monoocular and biocular double vision. The cataract should be suspected to exist in all patients with these symptoms. Diagnosis is made using the pupillary examination with a bio microscope with which blur is observed. In view of the findings and the current indications for surgery, an ophthalmologist advises surgery. There are two main types of cataract surgeries, intracapsular cataract extraction (ICCE) and extracapsular cataract extraction (ECCE). ICCE is now rarely performed, mainly on some trauma and subluxated and dislocated lens. Modern methods of cataract surgery include a traditional extra capsular cataract extraction that is rarely performed due to frequent postoperative complications. Phacoemulsification is a standard in cataract surgery. This method uses ultrasound probe with which the lens mass is broken, followed by their aspirations and installation of soft, flexible intraocular lenses (IOL) through a small incision corneoscleral cut with the size from 2.8 to 3.2 mm. This method has led to a significant decrease in postoperative complications, in reduced number of astigmatism, greater patient satisfaction and in better postoperative results. Recent methods of cataract surgery include the use of femtosecond laser and coaxial and bimanual microsurgical operations. After the operation, the IOL is built into pseudophakic eye. New generation IOL are divided into the monofocal which are generally the most commonly used and the multifocal ones. Through the gradual development of special IOL cataract surgeries refractive surgery has come into being.
