Para el estudio, los especialistas seleccionaron 24 ojos de 18 pacientes tratados con DTK. Ocho ojos con gran hiperopía recibieron 12 aplicaciones para coagulación; otros ocho con poca hiperopía fueron tratados con ocho aplicaciones; finalmente, los ocho ojos restantes con poca hiperopía fueron tratados de leve miopía inducida, en el ojo no dominate de la monovisión, con ocho aplicaciones. Se llevó a cabo un seguimiento mínimo de 18 meses.
La media de refracción cicloplégica, a los 18 meses, fue de 5,00 ± 0,38 dioptrías para el grupo de gran hiperopía; de 1,75 ± 0,19 dioptrías, para el grupo de poca hiperopía; y de 3,25 ± 0,27 dioptrías, para el grupo de presbiopía. La media de incremento de agudeza visual no corregida, a los 18 meses, fue de 8, 125 ± 2,1 líneas de Snellen, en el grupo de gran hiperopía; de 6,625 ± 0,744 líneas, para el grupo de poca hiperopía; y disminuyó 1,00 ± 1,85 líneas en el grupo con presbiopía.
