Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Summary

Toric posterior chamber phakic intraocular lenses (PC pIOLs) offer a safe and effective solution for vision correction in keratoconus patients. While improving refractive errors, higher-order aberrations may still affect overall visual quality.

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Refractive Surgery

Background:

  • Keratoconus is a progressive corneal thinning causing myopia and irregular astigmatism, significantly impacting vision quality.
  • Patients with keratoconus often experience visual disturbances like diplopia, halos, and ghost images.
  • Standard treatments may be unsuitable for some keratoconus patients, necessitating alternative interventions.

Purpose of the Study:

  • To evaluate the safety and efficacy of toric posterior chamber phakic intraocular lenses (PC pIOLs) for refractive error correction in keratoconus patients.
  • To assess the outcomes of PC pIOL implantation, alone or combined with other procedures, in managing keratoconus-associated visual impairments.

Main Methods:

  • The study involved implanting toric posterior chamber phakic intraocular lenses (PC pIOLs) in keratoconus patients unsuitable for other procedures.
  • Procedures were performed off-label with specific patient informed consent.
  • Data from several reports were aggregated to assess safety and efficacy.

Main Results:

  • Reports indicate that toric PC pIOL implantation is a safe procedure for keratoconus patients.
  • The efficacy of PC pIOLs in correcting refractive errors associated with keratoconus is supported by available data.
  • Corneal higher-order aberrations remain a factor influencing the final visual quality post-procedure.

Conclusions:

  • Toric PC pIOLs represent a viable surgical option for keratoconus patients with limited treatment alternatives.
  • The procedure demonstrates safety and efficacy in addressing refractive errors.
  • Further consideration of corneal higher-order aberrations is necessary for optimizing visual outcomes in these patients.
