[Correction of high-degree hyperopia by multiple pseudophakia].

The present study was undertaken to create a physicomathematical model of multiple pseudophakia and to investigate its method in correcting high-degree hyperopia. On the basis of the calculation of spherical aberrations, the authors have proposed recommendations for combining intraocular lenses (IOL), as well as developed and tested the modified formula for calculating the focal power of intracapsularly implanted IOLs. They provide a rationale for the increased clearly visible space depth phenomenon observed in patients with multiple pseudophakia and have calculated the reflection light energy loss caused by the presence of two artificial lenses.

[The possibility of performing laser interventions after the implantation of posterior chamber intraocular lenses].

The possibility of YAG laser interventions on the posterior capsule of the lens with subsequent argon laser coagulation of the retina in patients with aphakia and artiphakia is studied. The optimal intervention for secondary cataract in patients with artiphakia is circular resection of the posterior capsule. Intraocular lenses prevent such complications as vitreous hernias and allow creating a larger and better shaped opening in the posterior chamber, thus providing a better access for laser coagulation of the retina.

[Changes in the drainage system of the eye during hydromonitoring exposure].

A hydromonitoring exposure with a high-velocity pulsed liquid jet aimed into Schlemm's canal lumen and a similar exposure with a syringe at a 60 H pressure on piston were carried out in isolated eyes. Examinations of stained sections showed that hydromonitoring exposure at a pressure of 1 to 5 techn. atm.

[Refraction ring-shaped tunnel keratoplasty in the correction of high-degree myopia].

A new method has been developed for diminishing the myopic eye refraction: refraction ring-like tunnel keratoplasty. The technique is simple, virtually atraumatic, and highly effective. It has been introduced in clinical practice.

[Theoretical aspects of and technological equipment for hydromonitored microsurgery of the eye].

A new method of removing the cataracta and vitreous body, called less than hydromonitor greater than is grounded theoretically. It is based on the use of destructive properties of superthin, high-speed liquid spray, affected pathological intraocular structures. Surgical tools and a hydro-drive system have already been developed for the accomplishment of hydromonitoring method.
