14 Medical Condition Being Studied

aphakia

15 Intervention

i Types of intervention

Device

Please specify

ii Description/ name of Intervention/article

Artisan aphakia intraocular lens implant

iii Dosage form of the intervention

One intraocular lens per patient recruited into study

iv Dosage of the intervention

No dosage as this is a medical device not a drug

v Duration of the intervention

Intraocular lens remains inside eye indefinitely unless (due to complications) lens need replacing

vi Frequency of the intervention

A single surgical procedure

16 Comparative Treatments

i Description/ name of comparative treatments

Scleral fixation aims to fixate the IOL in the physiological location despite of a more skill demanding procedure. Iris fixation using claw shaped haptics attached to the mid-peripheral iris allows easy and fast IOL placement through the original main phacoemulsification incision.

ii Dosage form of the comparative treatments

Other commonly used intraocular lenses work in a similar manner. A single surgical procedure is used to implant the lens which remains inside the eye indefinitely.

iii Dosage of the comparative treatments

A single intraocular lens implanted per eye.

iv Duration of the comparative treatments

The lens implant remains inside the eye indefinitely

v Frequency of the comparative treatments

A single surgical procedure is performed to implant the intraocular lens
