Modern Cataract Surgery

Mr Hadi Zambarakji, Consultant Vitreoretinal and Cataract surgeon at the Spire London East Hospital and The Holly Private Hospital looks at the patient’s journey and decision-making process involved in today’s modern cataract surgery.

 

Tips

Myopic patients do not like to lose their excellent near vision, especially if not yet presbyopic. Hyperopic patients, on the other hand, do not see well at any distance so tend to be pleased if the post-operative unaided visual acuity is improved for distance. Astigmatic patients will not have good unaided visual acuity after surgery if the astigmatism is not corrected so sometimes a toric lens implant may work best (look out for the next newsletter about issues relating to toric lens implants!).

Lifestyles are important to discuss with the patient. We need to know about the patient’s hobbies, activities and sports interest. Do they fish and play golf, do they play any music instruments or are they an outdoor/indoor person. How much time in a day does the patient spend on the computer or are they the unofficial taxi driver driving children around all day from appointment to appointment. It is also really important to find out about night driving especially if a patient is a professional driver.

Patient expectations hold the key to planning a successful treatment and always discuss what the patient wants to get out of the surgery. Talk to them at length and listen to what they are saying not what you think they are saying. Surgery will often be a compromise and if you think the patient does not fully appreciate the compromises or that you cannot deliver what is required, there is no harm in deferring surgery.

 

Options for Surgery

Sometimes the patient is happy to wear reading spectacles after surgery and just wants correcting for distance. If this is the case, a monofocal lens implant would be most suitable.

Monofocal lens implants are also used to correct for distance in one eye and near in the non-dominant eye (this is called monovision), which gives good spectacle independence in many patients, but poor stereo-vision. For patients suitable for monovision correction, the Optometrist would ideally do a contact lens trial prior to referral, which gives invaluable information about the proposed treatment plan and type of lens implant to be used.

Multifocal lens implants are a great option but have certain compromises. Some patients suffer night vision difficulties like halos or glare. Night-time dysphotopsias are another possible complication of multifocal lens implants that give the patient unwanted images such as flashes, starbursts and halos. Intermediate vision tends to be limited with multifocal lens implants, despite good distance and near vision therefore computer vision may be compromised.

Patients who drive much at night are usually not good candidates for multifocal lens implants be-cause of the above night-time issues resulting form the pupil dilating in the dark.

A newer type of lens called the extended depth of focus (EDOF) lens implants will give good dis-tance and intermediate vision but with poor near vision. With the EDOF lens implants, I would tend to aim for a low myopic outcome in the second, non-dominant eye to achieve slightly better near vision. The trade off here is that the distance vision will be compromised in the non-dominant eye. The night vision complications of EDOFs are much the same as for multifocal implants.

Trifocal lens implants are also popular giving a good range of vision, but are not so forgiving if the patient has a degree of residual astigmatism and night vision issues will be the same as multifocal implants.

 

Referral Tips – Please include

  • Refraction – Hyperopia / Myopia / Astigmatism
  • Cornea – K readings
  • Degree and type of cataract
  • Hobbies
  • Occupation
  • Need for driving at night
  • Glaucoma
  • Risk Factors:
    • Glaucoma / retina
    • Tamsulosin / Doxazosin or other alpha blockers

 

 


  1. I just wanted to write to say how fantastic Hadi (I called him this as I couldn’t pronounce his last name) and his team are!

    I recently had Cataract surgery on both of my eyes and it has transformed my quality of life. Hadi is the utmost professional and has a fantastic bed side manner. He is clearly at the top of his game and yet he is very humble and kind. He answered every question I asked and took great care to ensure I understood the options of Mono vs Vari and was very thorough in understanding what my expectations were.

    I can not speak highly enough of him and would recommend him to anyone without any reserve what so ever. I am lucky enough to have a wonderful and caring GP who put me in touch with Hadi as he had operated on him as well. A Doctor’s Doctor!

    Thanks again for making my outlook on life bright again!!

The CentraSight treatment programme uses a tiny telescope, which is implanted inside the eye to improve vision and quality of life for individuals affected by end-stage age-related macular degeneration. The above link allows the patient to find the necessary information about this program. Mr. Hadi Zambarakji is currently in the process of developing a patient pathway and will be offering with CentraSight this new technology to his patients.
