Medical Sciences, 44(2017) :103-120International Scientific Symposium What’s New in Refractive Eye Surgery (range 0,03 to 0,18), coma 0,18±0,10µm (range 0,07±0,21), and spherical aberration -0,05±0,07µm (-0,14 to 0,07). In previous hyperopic eyes average UDVA 0,05±0,08Log-MAR (range 0,2 to 0,0), average UNVA was 0,06±0,07LogMAR (range 0,2 to 0,0) and SE was -0,12±0,20D (range -0,50 to +0,25D).Average values of trefoil were 0,13±0,08µm (range 0,06 to 0,24), coma 0,23±0,10µm (range 0,10 to 0,28) and spherical aberration -0,02±0,13µm (range -0,15 to 0,08).Conclusion: Implantation of multifocal IOLs after previous keratorefractive sur-gery offers satisfactory postoperative results. Further refinement in IOL power calcu-lations is needed to improve refractive outcome.Keywords: keratorefractive surgery; cataract surgery; multifocal intraocular lens; IOL power.TORIC  MULTIFOCAL  AND  ExTENDED  RANGE  OF  VISION  INTRAOCULAR  LENSES  IN  CORRECTION  OF  ASTIGMATISM  AND  PRESbYOPIAAnte barišić, Iva Dekaris, Nikica Gabrić, Neven miličićSpecial Eye Hospital “Svjetlost”, Department of Ophthalmology, School of Medicine, University of Rijeka, Zagreb, CroatiaModern cataract surgery is becoming refractive surgery. Patient’s expectations are growing and they wish to be free of spectacles as much as possible. Postopera-tive astigmatism is the main reason for patient’s dissatisfaction after implantation of multifocal intraocular lenses or extended range of vision intraocular lenses. Resid-ual astigmatism more than 0,5 dcyl will decrease quality of vision in such patients.“With the rule” astigmatism of 1.00 dcyl or less can be corrected with intraoper-ative incision at steep axis. Incision in corneas with “Against the rule” astigmatism is almost completely neutral and in these patients, we have to consider toric lenses even with 1.00 dcyl of astigmatism.Toric intraocular lenses can correct low to high amount of astigmatism. They spread indications for use of presbyopia correcting lenses. (multifocal or extended range of vision intraocular lenses). Patients suitable for toric presbyopia correcting lenses are those with astigmatism more than 1.00 or 1.25 dcyl, depending on axis and the patient’s age. Effect of incision on younger corneas is weaker than older ones. Toric presbyopia correcting lenses should be used only in patients with regu-114Rad 530.

All patients were free of any spectacles three months after the surgery.Another clinical study in Eye Hospital Svjetlost, with implantation of toric Ex-tended range of vision IOLs to 24 patients in both eyes showed reduction of mean astigmatism from 2,85±0,56 D to 0,25±0,24 D and only two patients have to wear reading glasses for small print.In conclusion, we can say that toric presbyopia correcting intraocular lenses can correct astigmatism and presbyopia and enable patient’s high spectacle independ-ence.Keywords: toric intraocular lenses; extended range of vision lenses; astigma-tism; presbyopia.REFRACTIVE  LENTICULE  ExTRACTION  IN  TREATmENT  OF  SHORT-SIGHTEDNESS  WITH  OR  WITHOuT  ASTIGmATISmNavid ArdjomandSehzentrum für Augenlaser Graz, AustriaRefractive surgery has gained high popularity within the last 20 years. One of the main reasons for the success story of recfractive surgery is the high quality of laser technology in corneal surgery. Zeiss company introduced around 10 years ago the latest step in corneal refractive surgery: “Refractive Lenticule Extraction (ReLEx - SmILE)”.This technique is suitable for myopia up to 10 D and astigmatism up to 5 D. Hyperopia treatment is under clinical investigation at the moment and commer-cially not available yet. ReLEx - SMILE has the advantage of a very short operation time, the need for only one femtolaser, a very fast visual recovery time and a very low complication rate.
