According to the latest statistics, 43% people in Hong Kong are suffering from presbyopia (loss of near and intermediate vision), and the number is expected to further increase due to the aging population. To better serve patients' needs, Hong Kong Sanatorium & Hospital (HKSH) introduces comprehensive presbyopia treatment that doctors can choose the most appropriate treatment for patients based on their requirements.

Refractive Surgery on Cornea - Laser Refractive Surgery or Implantation of Intra-Corneal Implant :

• Laser Refractive Surgery on cornea can correct myopia, hyperopia and presbyopia problems. It is a safe option, but it may not completely correct the underlying problem and the patient's presbyopia may progress again, requiring another treatment.
• Implantation of Intra-Corneal Implant is safe but not as effective as Lens Exchange.

Lens Exchange is the most thorough treatment among all, which removes the patient's lens and implants an IOL. Patients can choose between Monofocal IOL, Multifocal IOL and the newly introduced Accommodating IOL.

• Monofocal IOL: Can only deliver improved vision at one distance (usually far) and thus patients will probably need to wear glasses for nearer and intermediate vision after surgery.
• Multifocal IOL:Project multiple images, requiring patients' brain to adjust. Some patients may have difficulty adjusting to the new vision. Besides, intermediate vision can be weaker because the technology is designed mainly for near and distance vision. Patients may experience halos and glares problems.
• Accommodating IOL: It was modelled after the human eye. Like the natural lens, it uses the eye muscle to flex and accommodate in order to focus on objects in the environment at all distances. It can treat presbyopia and cataract at the same time.
