Summary
Achieving target refraction post-cataract surgery is key for patient satisfaction. This study found all three monofocal intraocular lenses (IOLs) were stable, but IOL design slightly impacts refractive predictability.
Area of Science:
- Ophthalmology
- Biomedical Engineering
Background:
- Accurate postoperative refractive outcomes are vital for visual quality and patient satisfaction after cataract surgery.
- Residual refractive errors can negatively impact the patient experience.
Purpose of the Study:
- To evaluate the relationship between preoperative target refraction, intraocular lens (IOL) shift, and refractive stability.
- To compare the refractive predictability of three different monofocal IOLs.
Main Methods:
- Prospective observational study of 94 eyes undergoing cataract surgery with monofocal IOL implantation (PCB00, RayOne HA, Akreos Adapt).
- Preoperative biometry included axial length, anterior chamber depth, central corneal thickness, and white-to-white distance.
- IOL position and refraction were measured at 1 week, 1 month, and 6 months postoperatively; patient satisfaction was also assessed.
Main Results:
- All three IOLs demonstrated stable in-the-bag positioning with minimal longitudinal shift over 6 months (p > 0.05).
- Postoperative refractive outcomes were comparable, though RayOne HA showed a trend towards myopic deviation, while PCB00 and Akreos Adapt stayed closer to emmetropia.
- Statistically significant intergroup differences in deviation from target refraction were observed at 1 month (p = 0.004) and 6 months (p = 0.045).
Conclusions:
- All evaluated monofocal IOLs offer stable positioning and good visual outcomes.
- Subtle differences in IOL design may influence refractive predictability, suggesting potential benefits from tailoring target refraction to specific IOL types.
- Optimizing target refraction based on IOL choice could enhance the achievement of emmetropia and improve patient satisfaction.

Focusing 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...
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.

Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
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...
Ophthalmic Drug Delivery Systems
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
