OBJECTIVES: To describe the results obtained in the extraction of the transparent crystalline lens in hypermetrope patients. METHODS: A longitudinal, prospective and descriptive study was conducted from September, 2009 to February, 2010. Sixty eyes was studied from 30 patients presenting with hypermetropy who came to "Ram162n Pando Ferrer" Cuban Institute of Ophthalmology due to they not fulfilled the criteria established for corneal refractory surgery. Hoffer W by IOL master formula was applied for estimation of intraocular lens, standard surgical technique, phacoemulsification (phacoaspiration), ultrasonic power: 10% (pulsed), empty: 350 mm Hg, flow: 25 cc/min; corneal tunnel, wide capsulorrhesis and implant of monofocal intraocular lens in capsular sac. For paired data a statistical analysis by t-test associated average was carried out. RESULTS: Mean age was of 39 ± 2,6 years. The mean axial length was of 21 ± 2 mm. The better visual acuity without correction rise of 0,08 in the preoperative period to 0.72 in the postoperative one. The better visual acuity with correction varied from 0.92 to 0.98. The value of sphere decreased from 5.25 to 0.50 and the cylinder from 0.75 to 0.25 dioptres; consequently, the spherical equivalent decreased from 4.75 in preoperative period to 1,00 dioptres in the postoperative one, specifically in the dominant eye to 0.46 and in the non-dominant one to -0.97 dioptres. CONCLUSIONS: Monovision is effective in the patients. The extraction of transparent crystalline lens in patients with hypermetropy is a useful option when they are not candidates to corneal refractive surgery.
