Cataract Surgery After LASIK eye procedure requires special expertise. There are many important points to think about. Lets divide the factors to consider into three groups. Calculations before Cataract eye procedure, Techniques during the cataract surgery and management after the cataract eye surgery.
Calculations before Cataract eye procedure
Its very important get certain data before proceeding with cataract eye surgery.
- Length of the eye: This can be measure by ultrasound or laser. Laser detection with Iol Master or Lenstar.
- Curvature of the cornea: This is where the fun and headaches begin. Lasik eye surgery changes the relationship between the front curvature of the cornea and its back curvature.
- Power of the cornea: Detecting the true power of the Cornea is the holy grail of determing Iol power for emmetropia in patients undergoing cataract surgery after lasik eye surgeries.
- Distance between cornea and the lens: Also known as anterior chamber depth.
Techniques during the cataract surgery
The style of removing the cataract and inserting the new lens.
- Laser Or Manual Cataract Surgery: Will laser make corneal incisions too close to the flap?
- Type of Implant – Monofocal or PIE: We need to to asses the optical zone on Corneal topography. Corneal pachymetry map needs to be evaluated.
- Which PIE will work best for that eye: Crystalens or Tecnis multifocal could be an option. Some patients have loved the Restor.
Management after the cataract eye surgery
Correcting the residual refractive errors by laser or limbs relaxing incisions may be required. Aggressive management of dry eyes is essesntial.
LASIK eye surgery involves reshaping your cornea to correct a wide range of refractive errors – providing you with clear, sharp vision that either eliminates or greatly reduces your dependence on glasses and contact lenses. However, LASIK cannot prevent the development of cataracts later in life, since cataracts are a problem with the eye’s lens, not the cornea.
Because LASIK involves reshaping your cornea, you will need to consult with an experienced eye surgeon before undergoing cataract surgery in the future. Once your cornea is reshaped during LASIK, your cataract surgeon will need to perform a careful examination in order to determine the correct degree of power needed for your intraocular lens (IOL) – the artificial lens that is implanted during cataract surgery.
If an inexperienced surgeon takes the incorrect measurements, your vision may become out of focus following cataract surgery, requiring additional procedures to restore ideal vision. Thankfully, Dr. Khanna’s extensive experience with both LASIK and cataract surgery has equipped him with the skill necessary to accurately evaluate the changes in your eyes caused by LASIK surgery, ensuring the best possible vision with your IOL after cataract surgery. After removing the cataract, Dr. Khanna will perform a manifest refraction to determine the appropriate lens power for the IOL. Based on this information, the correct IOL will be implanted. You can read more about this topic in the bestseller book on cataract surgery.
