Intensity Pentafocal Intraocular Lens- Visual Outcome, Defocus Curve And Patient Satisfaction Analysis

we describe the postoperative visual outcome, defocus curve and visual function in patients that underwent cataract extraction with implantation of the new Intensity pentafocal Presbyopia correcting IOL

all patients underwent the operation and postoperative assessment at Maayan Medical Centre, Haifa, Israel.

We enrolled 12 patients, 16 eyes who underwent cataract surgery with the new Intensity pentafocal IOL implantation.

Exclusion criteria were postoperative best corrected visual acuity less than 0.8 LogMAR, and any intraoperative complication.

Patients’ evaluation included distance corrected and uncorrected visual acuity (DCVA, DUCVA), and near corrected and uncorrected visual acuity (NCVA, NUCVA), refraction and standard defocus curve. a patient  questionnaire was used assess patients’ satisfaction.

Sixteen eyes were enrolled.

Postoperatively, the mean DCVA was 0.04 (0.0-0.1) LogMAR, NCVA was 0.06 (0.0-0.4) LogMAR, DUCVA and NUCVA were 0.07 (0.0-0.2) and 0.4 (0.0-0.4) LogMAR, respectively.

A mean VA of 0.1(0.0-0.2) LogMAR was measured at a -1.0D and -1.5D defocus (corresponds to intermediate distance). Mean VA was 0.1 (0.0-0.5) LogMAR with a -2.5D defocus (near vision).

Using a questionnaire to assess patients’ satisfaction, most patients stated they have no difficulties performing tasks that require both near and distance vision.

two patients subjectively reported positive dysphotopsias

The data of the present study shows that Intensity IOL has a continuous defocus curve between +0.5D and -2.5D, with VA of 0.0-0.1LogMAR.  Intensity pentafocal, presbyopia-correcting IOL can correct presbyopia while achieving good distance and intermediate VA with minimal positive dysphotopsias.
