Research Details
  • Hydrophobic acrylic intraocular lenses (IOL) account for the majority of the market in the UK. In some patients microvacuoles known as glistenings are seen to form in the IOL material in the first 2 years after surgery. These do not affect visual acuity after surgery, but could cause light scatter in the eye and glare. They are seen more commonly clinically in eyes with damaged blood aqueous barriers, such as in diabetes or uveitis. Recently a new intraocular lens (AVS) which has a slightly higher water content (4% versus less than 1%) does not appear to develop glistenings. We plan to compare this IOL with a standard hydrophobic IOL in diabetic patients.

Study Design
Randomised controlled trial
Study Type

AVS hydrophobic intraocular lens versus AcrySof® intraocular lens. Patients will be randomised to have routine cataract surgery to one eye with implantation of either the Santen or the AcrySof® lens. Randomisation will be via a remote computer based website. Surgery to the second eye will be performed within 6 weeks of the first operation by the same surgeon, with the other intraocular lens type. Patients will be followed up for a total of 3 years.

Intervention Type
Primary Outcome Measures
  • 1. Glistenings
  • 2. Vision
  • Taken at 1, 3, 6, 12, 24 and 36 months.
Secondary Outcome Measures
  • 1. Post-operative inflammation after cataract surgery and cellular deposition on the IOL surface
  • 2. Objective optical quality and wave-front aberration
  • 3. Contrast sensitivity
  • 4. Diabetic retinopathy after cataract surgery
  • Taken at 1, 3, 6, 12, 24 and 36 months.
