The main purpose of this study is to assess the clinical outcomes and the subjective experience of 37 presbyopic patients, being 20 hyperopes and 17 myopes, treated with the Custom Q Optimized treatment.

A retrospective chart review was performed of 37 (20 hyperopes and 17 myopes) consecutive patients who underwent PresbyLasik procedure by a single surgeon (R.R.M.) between September 2012 and August 2013. The mean age of the patients was 45.54 years old in the myopic group and 46.83 in the hyperopic group of patients. Outcomes recorded 6 months postoperatively were uncorrected distance, near and intermediate visual acuities, contrast sensitivity (under photopic and mesopic conditions), defocus curves and the Q value.

The mean binocular visual acuity for both groups was –0.0363 logMAR, being -0.004 logMAR in the hyperopic group and -0.027 logMAR in the myopic group. The mean intermediate visual acuity was 0.245 logMAR. The results obtained when testing the near visual acuity were that 57.8% of patients were J1 or better, 78.9% were J2 or better, 94.7% were J3 or better and 5.2% were J5 or better. None of the patients showed a worse visual acuity than J5. All the patients showed contrast sensitivity within the standard normal range at low spatial frequencies and slightly reduced at high spatial frequencies both, under photopic and scotopic conditiond it was inferior in all the patients. Defocus curves results were similar to the results obtained with a monofocal intraocular lens.

Presbylasik customised treatments,  is an effective alternative for presbyopic patients. This treatment  increase the positive spherical aberration and therefore the depth of focus. As long as a multifocal cornea is not created this technique is not associated with halos and glare. We consider this treatment to be a viable option for presbyopia correction as long as it shows a good visual acuity at all evaluated distances giving high rates of spectacle freedom.
