About

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

Full 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.

Enrollment: 23 patients

Sex: All

Ages: 20+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Adults, 20 years of age or older at the time of informed consent, of either gender, diagnosed with bilateral cataracts;
2. Able to comprehend and sign a statement of informed consent;
3. Willing and able to complete all required postoperative visits;
4. Calculated lens power within the available range;
5. Planned cataract removal by phacoemulsification;
6. Potential postoperative BCDVA of 0.5 decimal or better in both eyes;
7. Subject with preoperative astigmatism < 1.0 D
8. Clear intraocular media other than cataract in both eyes;
9. The subject must be able to undergo second eye surgery within 30 days of the first eye surgery.

[Justification for the inclusion criteria]

1. and 5: Cataract extraction is the indication of the clinical study.
2. and 3: One of GCP requirements 4: Essential condition for implant of the investigational lens. 6, 7, 8 and 9: Conditions to minimize the potential non-IOL factors which may affect the visual acuity data

Exclusion criteria

[Exclusion Criteria Prior to Surgery] The patient who meets any criteria specified in the following 1) through 22).

1. Irregular corneal aberration that affects postoperative visual function as demonstrated by corneal topography;
2. Inflammation or edema (swelling) of the cornea affecting post-operative visual acuity;
3. Subjects with diagnosed degenerative visual disorders (e.g. macular degeneration or other retinal disorders) that are predicted to cause future acuity losses to a level worse than 0.5 decimal for BCDVA;
4. Subjects who may be expected to require ocular surgery (other than blepharo-surgery, laser surgery of fundus and YAG capsulotomy) during the study;
5. Previous refractive surgery;
6. Amblyopia;
7. Clinically severe corneal dystrophy (eg., epithelial, stromal, or endothelial dystrophy), keratitis, keratoconjunctivitis, keratouveitis, keratopathy, or kerectasia;
8. Diabetic retinopathy;
9. Extremely shallow anterior chamber, not due to swollen cataract;
10. Microphthalmos;
11. Current or previous retinal detachment;
12. Previous corneal transplant;
13. Recurrent severe anterior or posterior segment inflammation of unknown etiology;
14. Rubella or traumatic cataract;
15. Iris neovascularization;
16. Glaucoma or ocular hypertension;
17. Aniridia;
18. Optic nerve atrophy;
19. Planned clear lensectomy (no lens opacity)
20. Pregnancy, lactating or possible pregnant;
21. Participation in any clinical study (drug or device) within 3 months prior to participating this study, planned participation another clinical study during this study, or currently participating in another study.
22. Disqualified by the investigator or the sub-investigator because of physical or ophthalmic diseases.

[Exclusion Criteria During Surgery] The patient who meets any criteria specified in the following 1) through 7).

1. Mechanical or surgical manipulation required to enlarge the pupil;
2. Excessive iris mobility;
3. Significant vitreous loss;
4. Significant anterior chamber hyphema;
5. Uncontrollable intraocular pressure;
6. Zonular or capsular rupture or tear;
7. IOL could not be fixed in the lens capsule;
