Abstract

The invention discloses a femtosecond laser cataract surgery treatment device which comprises an optical coherence tomography scanning imaging system, a data processing system, a laser light source system, a laser energy detection system, a laser scanning system and a press mirror. The laser light source system is provided with a femtosecond laser. The laser light source system and the laser energy detection system, the laser energy detection system and the laser scanning system, the laser scanning system and the optical coherence tomography scanning imaging system are respectively connected through a light beam transmission system. The femtosecond laser cataract surgery treatment device has the advantages that the device is precise, efficient and safe, and astigmatism and endophthalmitis after operation are avoided; envelope tearing and suspensory ligament injury are reduced, surrounding tissue injuries are small; complications produced during crystal nucleus emulsification and artificial lens implantation are decreased as far as possible; the operating difficulty is reduced; the required energy for ultrasonic emulsification is greatly decreased, and the corneal endothelium is effectively protected.

Description

technical field [0001] The invention belongs to the technical field of medical equipment and instruments, and relates to equipment and instruments for ophthalmic surgical treatment. More specifically, the invention relates to a femtosecond laser cataract surgical treatment device. Background technique [0002] According to a 2004 survey by the Eye Disease Prevalence Survey Group (EDPRG), 20.5 million people in the United States suffered from cataracts in 2000, and it is estimated that 30 million people will suffer from or will soon suffer from cataracts by 2020. According to the estimation of our health department, the number of cataract operations in my country in 2005 was about 510,000. [0003] According to the observational study on the incidence of cataract in southern India, WHO pointed out that in developing countries, there is one case of new cataract per 1000 people per year. According to the Chinese population, there are 1.2 million new cataract patients every yea...
