研究目的

Investigating the therapeutic effects of a new technique of energy cataract surgery with the simultaneous use of two wavelengths of laser emission acting as high-intensity laser—endodissector (Nd:YAG, wavelength λ = 1.44?μm) and a low-intensity laser—endobiostimulator (He–Ne, wavelength λ = 0.632?μm).

研究成果

The proposed new cataract extraction technology with combined use of two lasers (DW LCE) is the safest and exclusively laser technology. It has a number of unique properties that are not available in other known methods, both laser and ultrasound cataract surgery. It is possible to destruct the lens of any density degree without involving ultrasound and without manual mechanical fragmentation. The energy of Nd:YAG (λ = 1.44?μm) laser provides splitting and spalling of the eye lens core. Surgical and therapeutic-prophylactic laser treatment are simultaneously produced. The energy of this laser does not go beyond the eye lens. There is no vacuum load on the eyeball, compressional applanation of the cornea and hemorrhage around the cornea. There is no separation of the operation into the preliminary softening and subsequent destruction. The ergonomics of operation is comfortable for doctor and patient. The greater effectiveness and safety of laser surgery in comparison with ultrasound is explained by the peculiarities of surgical technique and the physical properties of Nd:YAG (λ = 1.44?μm) laser energy.

研究不足

The study does not address the long-term effects of the DW LCE technology beyond 12 months post-operation. Additionally, the specific percentage of the positive effects from the biostimulation laser action cannot be determined using only the clinical methods.
