Study Arms (1)

Mix and matched patients

EXPERIMENTAL

Mix and matched patients will get phacoemulsification with multifocal intraocular lens implantation with two different add power (+2.75 diopters (D) or +3.25 D, respectively) in each eye of a patient, contralaterally.

Device: Phacoemulsification with multifocal intraocular lens

Interventions

Phacoemulsification and implantation of a multifocal intraocular lens (IOL) with two different add power (+2.75 diopters (D) or +3.25 D, respectively) in each eye of a patient, contralaterally. They're called mix and matched patients.

Eligibility Criteria

Age20 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age-related cataract
  • Adult at the age of 21 or older at the time of the pre-operative examination and willing to have surgery on their 2nd eye within 7-28 days of their 1st eye.
  • A patient has the visual potential of 20/25 or better in each eye after cataract removal and IOL implantation.
  • A patient with preoperative corneal astigmatism from IOL Master less than 1 diopters
  • Written informed consent to surgery and participation in the study

You may not qualify if:

  • Pregnant woman and lactating woman
  • A patient with history of retinal disease
  • A patient with history of ocular trauma or ocular surgery (Intraocular surgery, refractive surgery, ocular surface surgery) in either eye
  • A patient with evidence of keratoconus or significant irregular astigmatism on pre-operative topography in either eye.
  • A patient that has been wearing PMMA lenses within 6 months, gas permeable lenses within one month, or extended -wear or daily soft contact lens within 7 days of their scheduled surgery.
  • Those with other diseases that can affect capsule stability such as pseudoexoliation syndrome, glaucoma, traumatic cataract, or marfan syndrome
  • Those who are not able to read and understand the informed consent (illiterate or foreigners)
