title: IOL Tetraflex, KH 3500--presbyopia treatment.
abstract: BACKGROUND
  Presbyopia is a loss of accommodative capacity of the eye determined by age. The possible solutions for its treatment are spectacle correction (mono-, bi- or multifocal), multifocal contact lenses, conductive keratoplasty, excimer laser surgery and surgical solution - CLE.
  
  
  OBJECTIVE
  Four-year experience with using LOL Tetraflex KH 3500 by Lenstec.
  
  
  METHODS
  Between 2005 and 2009, 71 eyes of 35 patients with the average age of 52 were operated at the private ophthalmological clinic 3F Microsurgery of the Eye in Kosice. The patients were selected by strict indication criteria recommended by the producer. We have evaluated the ability of the implanted lens to substitute for the presbyopic correction. The subjective criterion of patient's evaluation was the expression of content in common life situations on the scale of 1 to 10. The objective evaluation was constituted by the measurement of the accommodation width, the presence of PCO, its solution by means of YAG capsulotomy and the subsequent influence on the pseudo accommodative capacity of the lense.
  
  
  RESULTS
  92% of operated patients expressed their complete satisfaction with the surgery results. By objective accommodometer measurement, we have identified the average accommodation width of +1,5 dioptres on the operated eyes. The presence of PCO was discovered in 42,2% cases. All cases were treated by YAG Capsulotomy. By further observation we have tried to determine the influence of YAG Capsulotomy on the accommodation width and pseudo accommodative capacity of the eye.
  
  
  CONCLUSIONS
  The selection and use of TETRAFLEX lens is an appropriate alternative to presbyopia treatment with suitable patients.
