Dr Loh performs the following surgeries:

  • Cataract Surgery 
  • Cataract Surgery combined with Retina Surgery
  • Vitreo-Retinal Surgery
  • Pterygium Surgery
  • Minor Surgery: Incision and Drainage of Chalazion.

Cataract Surgery is an operation to remove the Cataract (clouding of lens) and insert a new lens implant into the eye. It is performed using Phacoemulsification – ultrasound energy to break up the Cataract). Femtosecond Laser is used in selected cases to assist in the Cataract surgery.

Types of lens implant used are:

  1. Monofocal lens implant;
  2. Toric lens implant – allow for correction of Astigmatism;
  3. Multifocal lens – allows for correction of Presblyopia (‘Lao Hua Yan’ or inability to read without reading glasses); and
  4. Multifocal toric lens – allows for correction of Presblyopia and Astigmatism.

Cataract Surgery combined with Retina Surgery is performed in cases where the patient has Cataract and Retinal conditions such as Diabetic Eye, Epiretinal Membranes, Macular Hole, Vitreo-Macular Traction and Vitreous Hemorrhage. By treating a patient’s Cataract and Retinal conditions at the same time, the patient’s vision can be improved over a shorter period of time.


Vitreo-Retinal Surgery is performed to treat Retinal Detachment, Macular Hole, Epiretinal Membrane and Vitreous Hemorrhage.

There are 2 major types of vitreo-retinal surgery:

(a) Vitrectomy – This is a type of key hole surgery, done through the back of the eye, to remove the Vitreous (jelly-like substance within the eyeball) and to repair any damage of the Retina.  Dr Loh uses Sutureless Vitrectomy which involves less cutting of tissue. This helps to reduce patient discomfort and surgery time and allows for faster patient recovery.

(b) Scleral Buckling – This involves sliding a silicone band around the eyeball to exert an pressure on the eyeball. This can help to stabilise the retina within the eyeball. Dr Loh’s surgery involves less manipulation of tissue to shorten surgery time and reduce patient discomfort.


Pterygium Surgery is performed to remove the Pterygium (abnormal growth of tissue on the eye surface). Dr Loh will do an excision to remove the abnormal tissue growth, followed by grafting tissue from a normal part of the eye and transferring it to the excised area. This is done to improve recovery and reduce chances of recurrence of recurrence of the growth.


To treat Chalazion (growth on the eyelid), minor surgery is required. An incision is made to drain out the contents of the growth. This allows the eyelid to recover and reduces the chance of recurrence of the growth.
