Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study is designed as a post market evaluation of the Softec HP1 IOL for continuance of the CE certificate. The primary effectiveness endpoint is to evaluate the safety and performance levels produced by this IOL in patients requiring standard cataract surgery. There will be no change from standard procedure, other than 1 extra post op evaluation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Recruitment will be performed by the 3 Clinical Investigators (Jean-Pierre Danjoux - Sunderland Eye Infirmary, Karen Goodall - Croft Shifa Health Center, Mark Benson - Midland Eye Institute) and any appropriate, pre-trained staff within the hospital using the inclusion and exclusion criteria set out in the protocol. Patient selection will involve anyone over the age of 21 with an age-related cataract regardless of ethnicity, religion or gender.

An Informed Consent Form (ICF) will be explained with patients in full which will be signed by both the Principal Investigator (PI) and the patient with full understanding. Understanding fully means that the patient understands the nature of the operation, the benefits to the operation and also any risks or burdens.

The consent form also states alternatives to participation in the trial other than the option being put forward. The patients will be of sound enough mind to retain the information from the ICF and will be given time to digest this in order to make a free and effective decision to join the study.

All risks and benefits are explained in the ICF and are no more or less than that of a standard cataract surgery provided on a daily basis by NHS consultants. All surgeries will be performed by the PI.

Confidentiality shall be kept at all times with the PI and clinical staff using a unique patient reference number that in no instance indicates the identity of the patient to the study sponsor (Lenstec Inc.) or anyone else outside of the hospital. Any other confidentiality issues will run in conjunction with the hospital policy of which the staff involved in the study are aware.

There are no tissue samples to be used in this study.

Softec HP1 Intraocular Lens

The Softec HP1 IOL is a single-piece, biconvex, ultraviolet absorbing intraocular lens designed for insertion into the posterior chamber of the human eye for visual correction of Aphakia in adults over the age of 21, and as a replacement of a damaged (cataract) natural lens.

Group Type OTHER

Softec HP1 Intraocular Lens

Intervention Type DEVICE
