Summary

TLDRLASIK is an outpatient surgical procedure to reduce dependency on glasses or contact lenses by reshaping the cornea. It involves numbing the eye, creating a corneal flap with a microkeratome, and using an Excimer laser to reshape the cornea. The procedure is quick, requires no stitches, and includes post-op care with antibiotic drops and an eye shield. Arrange transportation as driving is not advised immediately after.

Takeaways

  • 👁️ LASIK is a surgical procedure to reduce dependency on glasses or contact lenses.
  • 🌟 The acronym LASIK stands for Laser Assisted In Situ Keratomileusis.
  • 🕒 The procedure typically takes about 15 minutes per eye.
  • 💉 Topical eye drops are used to numb the eye before the procedure.
  • 💊 A sedative may be given to help the patient relax.
  • 🔄 A lid speculum is used to hold the eyelid open during the procedure.
  • 🔧 A microkeratome is used to create a corneal flap by cutting a portion of the cornea.
  • ⚡ The Excimer laser is used to reshape the cornea by vaporizing tiny portions of its interior.
  • 🔄 The corneal flap is then replaced and observed for bonding.
  • 🏥 No stitches are required as the cornea heals rapidly.
  • 🚗 Arrangements for a ride home are necessary as driving is not recommended immediately after the procedure.

Q & A

  • What is LASIK and what does it aim to achieve?

    -LASIK, which stands for laser assisted in situ keratomileusis, is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses by permanently changing the shape of the cornea.

  • How long does a LASIK procedure typically take?

    -A LASIK procedure usually requires about 15 minutes per eye.

  • What is the role of the lid speculum in the LASIK procedure?

    -The lid speculum is used to hold the eyelid open during the procedure.

  • What sensation might a patient experience when the suction ring is placed on the eye?

    -Patients may feel pressure and experience dimming of their vision when the suction ring is placed on the eye.

  • What is a microkeratome and how is it used in LASIK surgery?

    -A microkeratome is a special device that is attached to the suction ring and uses a blade to create a corneal flap by cutting approximately the outermost 20% of the cornea.

  • How does the Excimer laser contribute to reshaping the cornea during LASIK?

    -The Excimer laser is used to reshape the cornea by vaporizing tiny portions of its interior, which usually takes less than 60 seconds.

  • Why does the cornea not require stitches after the procedure?

    -The cornea bonds quickly after the procedure, which allows for rapid healing without the need for stitches.

  • What measures are taken to prevent infection after LASIK surgery?

    -After the procedure, the doctor administers antibiotic drops to prevent infection.

  • Why is a protective shield placed over the eye after LASIK surgery?

    -A protective shield is placed over the eye to prevent the patient from rubbing it or putting pressure on it while sleeping.

  • Why can't patients drive immediately after LASIK surgery?

    -Patients cannot drive immediately following the procedure due to potential visual disturbances and the need for recovery.

  • What arrangements should be made for transportation after LASIK surgery?

    -Patients should arrange for a ride home since they will not be able to drive immediately after the procedure.
