  • Comment on: Impact of intraocular lens decentration and tilt on higher-order aberrations in patients with high and super-high myopia following cataract surgery
    Ankita Bandyopadhyay, Chaithu S Aimol, Suraj K Chaurasiya
    Indian Journal of Ophthalmology, 2026
    Dear Editor, We read with great interest the article titled “Impact of intraocular lens decentration and tilt on higher-order aberrations in patients with high and super-high myopia following cataract surgery,” published by Wang Y et al.[1] The authors offer valuable insights into a challenging population subset. However, we wish to highlight several methodological limitations and clinical considerations that warrant caution in interpreting and generalizing the results. The relatively small sample size, particularly in the super-high myopia group (n = 17), limits statistical power and may obscure meaningful associations. Furthermore, the 24% loss to follow-up (16 out of 66 patients) introduces potential attrition bias, which may skew the outcome measures.[2] The short follow-up period of only 3 months may not be sufficient to capture long-term changes in intraocular lens (IOL) position. Capsular contraction and zonular instability, especially in highly myopic eyes, often cause late decentration or tilt, affecting visual outcomes over time.[3] Although the use of CASIA2 anterior segment OCT system (Tomey Corporation, Nagoya, Japan) is commendable for its high-resolution measurements, assessments were conducted under photopic, undilated conditions. Higher order aberration (HOA)s were analyzed at a fixed 3 mm pupil size using the iTrace system, which does not reflect real-world mesopic or scotopic scenarios, where pupils dilate and visual symptoms such as glare and halos are more pronounced.[4] The study lacks stratification based on the severity of IOL malposition. Without categorizing outcomes by decentration or tilt magnitude, it becomes difficult to evaluate threshold effects or establish clinical guidelines.[5] Another notable limitation is the absence of subjective visual quality measures. Incorporating tools like the National Eye Institute Visual Function Questionnaire (NEI VFQ-25) or other patient-reported outcome metrics would better reflect functional vision and satisfaction, which do not always correlate with objective visual acuity or Modulation transfer function (MTF) scores.[6] The study exclusively evaluated a single IOL model (A1-UV), thereby limiting generalizability. Optical tolerance to decentration and tilt varies among different IOL design—monofocal, aspheric, multifocal, and toric—and some are specifically engineered to reduce HOAs under decentered conditions.[7] In conclusion, while the study emphasizes the critical role of IOL centration in visual quality for high myopes, future investigations should include larger, more diverse cohorts, longer follow-up durations, subjective patient-reported data, and comparative IOL models. These refinements will contribute to a more comprehensive understanding of IOL positioning effects and guide individualized surgical planning.
  • Objective Evaluation of Relationship Between Tear Film Stability and Visual Fatigue [Letter]
    Ankita Bandyopadhyay, Firdoos Jaman, Suraj Chaurasiya
    Clinical Optometry, 2025
    Between Tear Film Stability and Visual Fatigue" by Watanabe et al. 1 The authors investigate the association between non-invasive tear film break-up time (NIBUT) and binocular fusion maintenance (BFM) as indicators of visual fatigue a commendable effort, given the increasing clinical burden of digital eye strain (DES) in today's screen-dominant lifestyle.However, we wish to highlight certain methodological limitations and areas for improvement that would enhance the study's clinical relevance and scientific rigor.A key concern is the study's small sample size (n = 11) and restricted demographic (young, healthy adults).Dry eye disease and visual fatigue affect a wider population, including older individuals, people with refractive errors, and those with binocular vision disorders. 2The homogeneity of the sample limits the generalizability of the results.Future studies would benefit from including a more diverse cohort to better represent the population experiencing digital fatigue.The 30-minute screen task used in this study, although aligned with prior protocols, may not fully capture the temporal dynamics of ocular surface changes.Research suggests that visual discomfort and tear film instability tend to intensify with prolonged screen exposure, often beyond 30 minutes. 3 Additionally, compensatory mechanisms such as altered blink behavior or ocular surface exposure emerge more prominently with longer tasks.Including extended screen durations in future research would improve ecological validity.Another limitation is the exclusive reliance on NIBUT as an objective tear film parameter.Although NIBUT provides quantitative insight, the test requires patients to suppress blinking, which is inconsistent with natural screen use.Moreover, blink rate and blink completeness critical factors in tear film stability were not assessed.These parameters have been shown to significantly influence ocular comfort and tear dynamics during screen tasks. 4Incorporating eye-tracking or blink-monitoring tools would provide a more comprehensive evaluation of the ocular surface environment under screen stress.We also noted the absence of subjective symptom assessment tools, such as the Ocular Surface Disease Index (OSDI) or the Computer Vision Syndrome Questionnaire (CVS-Q).While the study aims to reduce reliance on subjective reporting, visual fatigue remains a subjective experience that is often not fully captured through objective testing alone.Validated questionnaires would allow correlation between measurable tear film changes and perceived discomfort, thereby enhancing clinical applicability. 5The correlation between NI-BUT and BFM (R = 0.385) is statistically significant, the modest effect size indicates the potential involvement of additional variables such as accommodative and vergence anomalies, both known contributors to DES.Evaluating parameters like accommodative amplitude, vergence ranges, and fixation disparity would help interpret the observed changes in binocular function more accurately.In conclusion, Watanabe et al present an important preliminary study linking tear film instability with visual fatigue.To advance the field, future studies should include larger, more heterogeneous populations, longer task durations, blink analysis, and validated symptom questionnaires, while considering the broader visual system.

  • Comments on "the effect of 2% pilocarpine on depth of field in different time intervals among presbyopic subjects"
    Suraj Kumar Chaurasiya, Pradeep Agarwal
    Indian Journal of Ophthalmology, 2025
    Dear Editor, I recently read the article titled “The Effect of 2% Pilocarpine on Depth of Field in Different Time Intervals Among Presbyopic Subjects” by Tripathi A et al.[1] with great interest. This study provides valuable insights into the pharmacologic management of presbyopia using pupillary miotics. However, I would like to highlight certain limitations and suggest improvements that could enhance the robustness of the findings and their applicability. The study’s methodology for measuring baseline depth of field (DOFi) does not include sufficient comparison with age-matched controls not using pilocarpine. As DOFi can vary based on environmental and physiological factors, the inclusion of a control group would have better contextualized the outcomes. Additionally, the subjective method of assessing DOFi, where participants indicate when they can or cannot see the chart clearly, introduces potential observer bias. Prior studies have shown that objective methods, such as wavefront aberrometry, offer more precise measurements and could have strengthened the study’s reliability.[2,3] The study attributes changes in DOFi primarily to pupil miosis without fully exploring the potential contribution of pilocarpine-induced accommodation. Research has shown that pilocarpine affects both pupil size and accommodative amplitude.[4] Objective accommodative response measurements, such as those obtained through autorefractometry or optical coherence tomography, could have provided a clearer understanding of the mechanisms involved. Furthermore, the study evaluated DOFi changes only within 45 min of pilocarpine instillation. While these results are insightful, the absence of longer-term follow-up limits the understanding of sustained efficacy and potential rebound effects. Investigations into the duration of pilocarpine’s effects are essential for assessing its practical clinical use. The study briefly mentions that some participants experienced mild to moderate headaches but lacks detailed data on their incidence or severity. Comprehensive documentation of adverse effects, as seen in related studies, is essential for a thorough evaluation of pilocarpine’s safety in presbyopia management.[5] In conclusion, while this study highlights the potential of pilocarpine in extending DOFi in presbyopes, addressing the aforementioned limitations would significantly enhance the scientific rigor and clinical relevance of the findings. These considerations could serve as a foundation for future research to advance pharmacological treatments for presbyopia. Financial support and sponsorship: Nil.

    It is important to be able to measure the range of clear focus in clinical practice to advise on presbyopia correction techniques and to optimise the correction power. Both subjective and objective techniques are necessary: subjective techniques (such as patient reported outcome questionnaires and defocus curves) assess the impact of presbyopia on a patient and how the combination of residual objective accommodation and their natural DoF work for them; objective techniques (such as autorefraction, corneal topography and lens imaging) allow the clinician to understand how well a technique is working optically and whether it is the right choice or how adjustments can be made to optimise performance. Techniques to assess visual performance and adverse effects must be carefully conducted to gain a reliable end-point, considering the target size, contrast and illumination. Objective techniques are generally more reliable, can help to explain unexpected subjective results and imaging can be a powerful communication tool with patients. A clear diagnosis, excluding factors such as binocular vision issues or digital eye strain that can also cause similar symptoms, is critical for the patient to understand and adapt to presbyopia. Some corrective options are more permanent, such as implanted inlays / intraocular lenses or laser refractive surgery, so the optics can be trialled with contact lenses in advance (including differences between the eyes) to better communicate with the patient how the optics will work for them so they can make an informed choice.
