Non-corrected astigmats appear to be naturally adapted to their astigmatism, and astigmatic correction significantly changes their perception of their neutral point, even after a brief period of adaptation.
The change in astigmatism correction is unpredictable.
It appears that this technique is safe, quick, and helpful in reducing preexisting astigmatism.
Thus, small axis rotations are not an obstacle for satisfactory astigmatism correction with toric IOLs.
The LAL can be adjusted postoperatively to correct residual astigmatism.
Both methods can reduce mild to moderate astigmatism.
Various factors that affect astigmatism correction have been identified in the literature.
Moreover, the effect of possible positive interactions of aberrations (astigmatism and coma) might be altered after recalibration to correction of astigmatism.
For correcting larger amounts of astigmatism, a combination of techniques can produce greater correction.
The triple centration technique was helpful in astigmatism correction by SMILE.

How does astigmatism affects gaze pattern during walking over obstacles?4 answersAstigmatism can impact gaze patterns during walking over obstacles by altering visual sampling strategies. Individuals with visual impairments, such as astigmatism, may exhibit changes in gaze behavior, potentially affecting their ability to navigate around obstacles safely. Research suggests that individuals with impaired vision tend to direct their gaze closer to their current position and spend more time fixating on obstacles. Moreover, under multitasking conditions, individuals with visual impairments, like astigmatism, may experience increased obstacle contacts due to changes in gaze behavior. Additionally, individuals with blurred vision, similar to the effects of astigmatism, may adopt more cautious strategies, such as looking longer and more frequently ahead of the obstacle, to reduce the risk of tripping during obstacle negotiation.
Grade correction, one of the easiest ways to make students smile, why?5 answersGrade correction is considered one of the easiest ways to make students smile because it provides them with valuable feedback and helps them improve their performance. When teachers correct students' work, it shows that they care about their progress and want to help them succeed. Students prefer teachers as correctors and expect correction for all types of errors. Additionally, the correction process allows students to learn from their mistakes and grow academically. It also boosts their confidence and motivates them to work harder. The smile correction device mentioned in the abstracts is unrelated to grade correction in the educational context. Therefore, the concept of grade correction making students smile refers to the positive impact it has on their learning and development.

Does subordinate level in face recognition demonstrated a lower average reaction of time?
5 answers
Subordinate-level face recognition typically shows faster reaction times compared to basic-level recognition, contrary to the usual trend in object categorization. This phenomenon is influenced by the discriminability of faces within the stimulus set, with faces being categorized more quickly at the subordinate level when they are distinct from each other. Additionally, experts in face recognition exhibit a downward shift towards recognizing faces at more specific levels of abstraction, such as identifying individuals like Bill Clinton, as quickly as identifying faces at a basic level like "human". Furthermore, neural mechanisms in the ventral visual pathway support the privileged status of certain subordinate-level categories of faces, such as peer faces, indicating enhanced neural responses and size in critical face-processing areas.
Does subordinate level in face recognition result in faster reaction?
5 answers
Subordinate-level face recognition can indeed result in faster reaction times. Studies have shown that individuals exhibit a subordinate-level advantage for faces, categorizing them more quickly than at the basic level. Furthermore, training in subordinate-level individuation of faces leads to improved recognition performance and enhanced activation of specific neural components, such as the expert N250. This advantage is not solely based on experience but also involves privileged representations of certain face categories, like peer faces, within the ventral visual pathway, supported by enhanced neural responses in critical face-processing areas like the fusiform area. Additionally, specialized processing for the most frequently encountered face classes, such as own-race faces, has been observed, leading to faster discrimination of these faces.

How does astigmatism affects gaze pattern during walking over obstable?
4 answers
Astigmatism can impact gaze patterns during walking over obstacles. Individuals with astigmatism may exhibit cyclic changes in focus to enhance visual performance. Moreover, downward gazing, often observed during walking for guidance, can enhance postural control and walking stability through anticipatory stepping control. This gaze behavior may serve to gather information for feedback mechanisms, promoting stability through reactive processes. Visual input plays a crucial role in maintaining upright posture during walking, contributing to head, trunk, and leg motion control. The nervous system leverages visual information to modify trunk and whole-body walking behavior, enhancing gaze stability, especially in individuals with severe vestibular loss. Therefore, astigmatism can influence gaze patterns during walking over obstacles by affecting visual performance, postural control, and stability mechanisms.
Can Toric intraocular lens improve biomechanics during walking?
4 answers
Toric intraocular lenses (IOLs) primarily aim to correct corneal astigmatism during cataract surgery, enhancing visual outcomes. While toric soft contact lenses have shown alterations in corneal biomechanical properties over time, the impact of toric IOLs on walking biomechanics post-surgery is not directly addressed in the provided contexts. However, studies on visual restoration after cataract surgery have shown significant improvements in gait patterns, including increased walking speed and joint motion range, leading to more efficient locomotion. Therefore, although not directly studied, the enhanced visual acuity provided by toric IOLs could indirectly contribute to improved biomechanics during walking by facilitating better navigation and sensorimotor integration in the elderly population undergoing cataract surgery.

Subordinate-level face recognition typically shows faster reaction times compared to basic-level or superordinate-level categorization, especially for faces, objects of expertise, or atypical objects. This advantage in subordinate-level processing is influenced by the discriminability of faces within the stimulus set. Additionally, the neural mechanisms underlying subordinate-level representations of faces involve enhanced neural magnitude and size in the fusiform area, supporting the privileged status of peer faces in identity recognition for emerging adults. Furthermore, expertise in face recognition relies on different spatial frequency information compared to expertise in object recognition, with face categorization at the subordinate level emphasizing low spatial frequencies, while expert car categorization focuses more on high spatial frequencies.
What age are suitable for multifocal IOL?
5 answers
Multifocal intraocular lenses (MIOLs) are suitable for various age groups based on different studies. For children aged 1-5 years with congenital cataract, bilateral implantation of multifocal IOLs significantly improves near vision and stereopsis compared to monofocal IOLs. In elderly patients undergoing cataract surgery, MIOLs that are minimally affected by pupil size are recommended to enhance daily functionality without glasses, improving quality of life post-surgery. However, in adults over 60 years old, a decline in corrected distance visual acuity (CDVA), distance-corrected near visual acuity (DCNVA), and near area-of-focus (AoF) has been observed with diffractive multifocal IOLs, indicating a decrease in visual outcomes with age. Therefore, while MIOLs can benefit various age groups, considerations should be made based on individual visual needs and age-related factors.
