Summary
Wavefront-guided LASIK (WFG-LASIK) and PRK (WFG-PRK) show excellent visual outcomes for myopia correction. Procedures performed by training fellows demonstrate high safety, efficacy, and predictability.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Surgery
Background:
- Myopia and compound myopic astigmatism are common refractive errors.
- Laser vision correction aims to improve uncorrected visual acuity.
- Wavefront-guided (WFG) technology offers personalized refractive error correction.
Purpose of the Study:
- To evaluate visual outcomes of WFG-LASIK and WFG-PRK.
- To assess safety and predictability of these procedures.
- To analyze outcomes when performed by cornea fellows in training.
Main Methods:
- Prospective, nonrandomized clinical trial.
- 33 patients (66 eyes) underwent WFG-LASIK; 36 patients (71 eyes) underwent WFG-PRK.
- Preoperative spherical equivalent up to -10.00 D; target emmetropia.
Main Results:
- WFG-LASIK: 91.2% achieved 20/20 UDVA, 35.3% achieved 20/15.
- WFG-PRK: 82.0% achieved 20/20 UDVA, 10.0% achieved 20/15.
- Both groups showed high predictability (91.2% and 98.0% within 0.50 D SE) and no loss of CDVA lines.
Conclusions:
- WFG-LASIK and WFG-PRK are safe and effective for myopia correction.
- Cornea fellows in training can achieve excellent results with these techniques.
- High predictability and visual acuity were demonstrated in both procedures.

01:27Open Angle Glaucoma: Treatment
938
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.

01:28Angle Closure Glaucoma: Treatment
1.1K
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...
