Study Details

Study Description

Brief Summary

To evaluate effectiveness and safety of the POD F GF Intraocular Lens (IOL) when implanted to replace the natural lens following cataract removal

Condition or Disease	Intervention/Treatment	Phase
Cataract; Lens Opacities; Presbyopia	Device: Assigned Intervention (POD F GF)	N/A

Detailed Description

Since the investigational lens, like conventional IOLs, is a posterior chamber lens which is widely implanted following cataract extraction, phacoemulsification is adopted. To assess the binocular vision, the investigational lens will be bilaterally implanted. Considering the safety of the study subjects, the time of implant to the remaining eye (2nd eye) will be decided based on the results of the 1st implant.

Outcome Measures

Primary Outcome Measures

1. Binocular Best corrected distance visual acuity (5 m) [Postoperative Day 120-180 (4-6 months)]

   CDVA measured with ETDRS charts placed in 5m distance with best aided corrective glasses according to ISO 11979-7:2014.

2. Binocular Distance corrected near visual acuity (40 cm) [Postoperative Day 120-180 (4-6 months)]

   DCIVA measured with ETDRS charts placed in 40cm distance with corrective glasses for far distance according to ISO 11979-7:2014.

3. Binocular Distance corrected intermediate visual acuity (80 cm) [Postoperative Day 120-180 (4-6 months)]

   DCIVA measured with ETDRS charts placed in 80cm distance with corrective glasses for far distance according to ISO 11979-7:2014.

Secondary Outcome Measures

1. Binocular photopic best corrected distance visual acuity (5 m) [Postoperative Day 120-180]

   DCIVA outcomes at 5m distance

2. Monocular and binocular photopic uncorrected distance visual acuity (5 m) [Postoperative Day 120-180]

   UDVA outcomes at n 5m distance

3. Monocular and binocular photopic uncorrected intermediate visual acuity and binocular distance corrected intermediate visual acuity (80 cm) [Postoperative Day 120-180]

   DCIVA outcomes at 80cm distance

4. Monocular and binocular photopic uncorrected near visual acuity and binocular distance corrected visual acuity (40cm) [Postoperative Day 120-180]

   DCNVA outcomes at 40cm distance

5. Binocular photopic defocus curves [Postoperative Day 120-180]

   To assess the visual acuity for different distances, defocus curves under photopic light conditions are measured. This test is performed with best distance corrected refraction and spherical additions ranging from -5.0 D to +1.5 D.

6. Contrast Sensitivity under photopic light conditions [Postoperative Day 120-180]

   Contrast Sensitivity outcomes under photopic light conditions

7. Contrast Sensitivity under mesopic light conditions [Postoperative Day 120-180]

   Contrast Sensitivity outcomes under photopic light conditions

8. Quality of Vison: VFQ-11 Questionnaire [Postoperative Day 120-180]

   Outcomes measures of a questionnaire to address the general patient satisfaction and possible side effects of the treatment. For this study, the validated and verified Visual Functioning Questionnaire - 25 (VFQ-25) will be used. The maximum score for each questionaire is 100.
