Summary
Refractive lens exchange (RLE) with toric intraocular lens (IOL) implantation effectively corrects astigmatism and refractive errors, achieving excellent visual acuity and high patient satisfaction.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- Preexisting astigmatism and ametropia can impair visual function.
- Refractive lens exchange (RLE) offers a surgical option for vision correction.
Purpose of the Study:
- To evaluate visual and refractive outcomes after RLE using toric intraocular lenses (IOLs).
- To assess the rotational stability of toric IOLs following RLE.
- To determine patient satisfaction and visual phenomena after the procedure.
Main Methods:
- A prospective, nonrandomized, observational case series of 32 eyes from 19 patients undergoing RLE with AcrySof Toric IOLs.
- Preoperative and 6-month postoperative measurements included uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and refractive error.
- Toric IOL axis shift, patient satisfaction, and visual phenomena were also assessed.
Main Results:
- 100% of eyes achieved 20/32 or better UCVA, and 84.3% achieved 20/25 or better.
- Mean refractive cylinder significantly decreased from -2.46 D to -0.53 D (P < .001).
- Mean toric IOL axis rotation was minimal (0.90 ± 1.76 degrees), with 96.8% of eyes showing rotation ≤5 degrees.
Conclusions:
- RLE with toric IOL implantation provides significant improvements in visual acuity and refractive error correction.
- The procedure demonstrates excellent rotational stability of the toric IOL.
- Patients reported high satisfaction with vision and minimal adverse visual phenomena.

01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
01:05Total Internal Reflection Fluorescence Microscopy
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.
01:28Angle 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...
