Conditions
Unspecified age-related cataract,
Registration Number
CTRI/2021/11/037924
Lead Sponsor
Carl Zeiss Meditec AG
Brief Summary

This study is a single-arm, prospective, multi-centric study on a long-term CE approved medical device. Patients planned for an aged-related cataract surgery will be contacted and invited to attend a preoperative visit up to 90 days prior to the surgery. The approved intra-ocular lens AT LISA 809M/MP will be implanted in the study eye. Afterwards the patient attends the standard-of-care follow-up visits with cataract surgery and two postoperative visits at 180 days (+/- 7 days) and 365 days (+/-14 days) after the surgery.

Inclusion Criteria
  • Patients of any gender, aged 18 years or older 2.

  • Patient is willing and capable of providing informed consent 4.
  • Patient is willing and capable of complying with visits and procedures as defined by this protocol.
Exclusion Criteria
  • Preoperative corrected distance visual acuity (CDVA) better than 0.3 logMAR (0.5 decimal) 2.
  • Endothelial cell count of less than 2000/mm2 3.
  • Ocular disorder that could potentially cause a clinically significant future visual acuity loss 4.

  • Clinically significant anterior segment pathology (e.g. chronic uveitis, iritis, aniridia, rubeosis iridis, anterior membrane dystrophies, poor pupil dilation, etc.) 6.
  • Clinically significant abnormal corneal finding (e.g. keratoconus, pellucid marginal degeneration, or irregular astigmatism, clinically significant corneal membrane dystrophies) 7.
  • Any clinically significant condition that could affect IOL stability (e.g. zonular dialysis, evident zonular weakness or dehiscence, etc.) 8.
  • Any History of clinically significant retinal pathologies or ocular diagnosis (e.g. diabetic retinopathy, ischemic diseases, macular degeneration, retinal detachment, optic neuropathy optic nerve atrophy, amblyopia, strabismus, microphthalmos, aniridia, epiretinal membrane etc.) that could alter or limit final postoperative visual prognosis 9.
  • Any acute infection (acute ocular disease, external/internal infection, systemic infection) 10.
  • Any previous intraocular and corneal surgery 11.
  • Uncontrolled glaucoma or IOP higher than 24mmHg under ocular hypertension treatment 12.
  • Current systemic or ocular pharmacotherapy that effects patients’ vision 13.
  • Current pathology or condition that could be a risk for the patient according to the investigator opinion 14.
  • Women during pregnancy and/or lactation 15.
  • Patients unable to meet the limitations of the protocol or likely of noncooperation during the trial 16.
  • Patients whose freedom is impaired by administrative or legal order 17.
  • Subject is enrolled in any other concurrent clinical study, with the exception of local mandatory governmental registries and observational studies/registries, that do not affect patients’ vision Note All eye-related inclusion and exclusion criteria are applicable to the study eye only.

Primary Outcome Measures
NameTimeMethod
Two co-primary effectiveness endpoints assessing the monocular corrected distance visual acuity (CDVA) and the monocular distance-corrected near visual acuity (DCNVA), will be analysed on a binary level (responder analysis). Responders regarding the two endpoints are defined as:6 Months
Responder regarding DCNVA:6 Months
Responder regarding CDVA: The achievement of a monocular CDVA of 0.3 LogMAR or better of the study eye, measured at 400 cm, 6 months after the implantation of the AT LISA 809M/MP.6 Months
The achievement of a monocular DCNVA of 0.3 LogMAR or better of the study eye, measured at 35 cm, 6 months after the implantation of the AT LISA 809M/MP.6 Months
Secondary Outcome Measures
NameTimeMethod
1.Monocular corrected distance visual acuity (CDVA)2.Monocular distance-corrected near visual acuity (DCNVA)
Secondary safety End Points1. IOL status
