AIM
To analysis of research hotspots and trends on the application of premium intraocular lens (PIOLs) in the past 2 decades.
METHODS
The literature search was performed on the Web of Science and included PIOLs studies published between January 2000 and December 2022. The retrieved literature was collated and analyzed by R-tool's Bibliometrix package, CitNetExplorer, CiteSpace and other software.
RESULTS
A total of 1801 articles about PIOLs were obtained, most of which were published in Spain and the United States. The organization that published the most articles was the University of Valencia in Spain. Alió JL, and Montés-Micó R, from Spain were the most influential authors in this field. The and were the core journals for this field; the top 10 cited articles mainly focus on postoperative satisfaction with multifocal intraocular lens (IOLs) and postoperative results of toric IOLs. Through the keyword analysis, we found that trifocal IOLs, astigmatism and extended depth of focus (EDoF) IOLs are the most discussed topics at present, and the importance of astigmatism and the clinical application of the new generation of PIOLs are the emerging research trends.
CONCLUSION
Bibliometric analysis can effectively help to identify multilevel concerns in PIOLs research and the prevailing research trends in the realm of PIOLs encompass the adoption of EDoF IOLs, trifocal IOLs, and their respective Toric models.

International Journal of Ophthalmology 2024To evaluate the visual and refractive outcomes in cases after sutured scleral fixation of existing subluxated or dislocated acrylic one-piece intraocular lenses (IOLs).
AIM
To evaluate the visual and refractive outcomes in cases after sutured scleral fixation of existing subluxated or dislocated acrylic one-piece intraocular lenses (IOLs).
METHODS
This study retrospectively enrolled a consecutive series of patients who underwent a surgery of sutured existing subluxated or dislocated IOLs from October 2018 to June 2020. All patients underwent comprehensive preoperative and postoperative ophthalmologic examination, and data were collected including age, sex, surgical indications, best-corrected visual acuity, refractive error, intraocular pressure. Presence of intraoperative and postoperative surgical complications was documented.
RESULTS
A total of 20 consecutive cases were enrolled for analysis with mean final follow-up period 9.8±5.3mo. Visual acuity improved from a mean of 0.35 (0.46±0.32 logMAR) preoperatively to 0.61 (0.21±0.18 logMAR) at the 3-month follow-up (=0.002). The mean amount of preoperative keratometric astigmatism and total postoperative refractive astigmatism was -1.24±0.80 diopters (D) and -1.42±0.97 D, respectively. There was no statistically significant difference between preoperative and postoperative astigmatism (=0.156). The mean IOL-induced astigmatism was -0.23±0.53 D. The mean spherical equivalent at the 3-month follow-up was -0.1±0.94 D. No major complications were noted during the follow-up period.
CONCLUSION
Surgical techniques using sutured scleral fixation of existing subluxated or dislocated acrylic one-piece IOLs result in favorable visual and refractive outcomes without major complications.

A retrospective cohort study was conducted to observe the correction effect of Toric intraocular lens (IOL) implantation in cataract eyes with specific types of irregular corneal astigmatism. Thirty-four eyes with either the "asymmetric bow-tie" pattern (Type I) or the "angled bow-tie" pattern (Type II) were included. Corneal topography was assessed using Pentacam HR, and changes in preoperative corneal astigmatism, visual acuity, manifest refraction, and objective visual quality were measured and compared. The average uncorrected distance visual acuity improved significantly from 0.86 ± 0.40 logMAR to 0.22 ± 0.15 logMAR (P < 0.001). Preoperative corneal astigmatism of 2.05 ± 0.90 D was corrected to a postoperative residual astigmatism of 0.78 ± 0.57 D (P < 0.001), with 32% of eyes within 0.50 D. The residual astigmatism prediction errors in Type I and Type II cases were (0.97 ± 0.68 D) and (0.66 ± 0.37 D), respectively (P = 0.100). The mean spherical equivalent prediction error in Type II cases (0.07 ± 0.36 D) was significantly smaller than that in Type I cases (- 0.29 ± 0.52 D) (P = 0.030). This study concludes that Toric IOL implantation effectively corrects specific types of irregular corneal astigmatism in cataract surgery. Eyes with the "angled bow-tie" pattern show higher accuracy in refractive predictions compared to eyes with the "asymmetric bow-tie" pattern.

Saudi Journal of Ophthalmology :... 2024To evaluate the clinical profile of amblyopia among patients referred to a tertiary care facility in Saudi Arabia.
PURPOSE
To evaluate the clinical profile of amblyopia among patients referred to a tertiary care facility in Saudi Arabia.
METHODS
All patients between 1 and 14 years presenting to the amblyopia clinic from 2016 to 2020 were retrospectively reviewed. Amblyopia was defined as visual acuity <0.2 LogMAR (20/30) in the worse eye or two-line difference between the two eyes. We classified patients into strabismic, refractive, mixed strabismic, and refractive and deprivation amblyopia. We subclassified our cohort according to age (< and ≥5 years).
RESULTS
Three hundred and eighty-three patients (199 male 54%) were seen in our clinic. Seventeen patients were excluded because they did not meet our inclusion criteria. The mean age at presentation was 5.05 ± 2.49 years. Strabismic amblyopia was found in 180 (49%), refractive in 101 (27.6%), mixed in 69 (19%), and deprivation in 16 (4.2%). Anisometropia in 85.25% and isometropia in 14.75%. Hyperopic astigmatism was the most common refractive error in 246 (67.2%). Esotropia was the most common deviation (90%). Strabismic amblyopia was significantly higher in the <5 years group (62.4% vs. 36.7%). While refractive amblyopia was significantly higher in ≥5 years group (38.8% vs. 15.7%) ( < 0.001).
CONCLUSION
Strabismic amblyopia was the most commonly diagnosed in our cohort, especially among patients <5 years of age. Refractive amblyopia was more common in older patients and may be under-detected due to the lack of proper vision screening. The implementation of proper vision screening should help in early detection and successful treatment at an early age.

BACKGROUND
This study aimed to compare the results of the Chronos binocular/monocular refraction system, that measures objective and subjective ocular refraction in one unit, to objective findings obtained from a conventional autorefractometer and a conventional subjective ocular refraction using a trial-frame in real space.
METHODS
Twenty-eight healthy volunteers (21.2 ± 1.5 years old) were included in this study. Objective ocular refraction was measured using two tests: the Chronos binocular/monocular refraction system under binocular conditions and a conventional autorefractometer under monocular conditions. Subjective ocular refraction was measured using three tests: Chronos binocular/monocular refraction system under binocular, monocular conditions, and trial-frame in the real space under monocular conditions. The measurement distance was set to 5.0 m for each test. All ocular refractions were converted into spherical equivalents (SEs).
RESULTS
The objective SE was significantly more negative with Chronos binocular/monocular refraction system under binocular condition (- 4.08 ± 2.76 D) than with the conventional autorefractometer under monocular condition (- 3.85 ± 2.66 D) (P = 0.002). Although, the subjective SE was significantly more negative with Chronos binocular/monocular refraction system under binocular condition (- 3.55 ± 2.67 D) than with the trial-frame in the real space under monocular condition (- 3.33 ± 2.75 D) (P = 0.002), Chronos binocular/monocular refraction system under monocular condition (- 3.17 ± 2.57 D) was not significantly different from that in trial-frame in real space under monocular condition (P = 0.33).
CONCLUSION
These findings suggest that the Chronos binocular/monocular refraction system, which can complete both objective and subjective ocular refraction tests in a single unit, is suitable for screening ocular refraction, although it produces slightly more myopic results. Furthermore, subjective ocular refraction testing accuracy in Chronos binocular/monocular refraction system can be equivalent to trial-frame in real-space testing by switching from binocular to monocular condition.

PURPOSE
To evaluate the long-term clinical outcomes of femtosecond thin-flap LASIK (femto-LASIK) for correction of refractive error after penetrating keratoplasty in keratoconus-affected eyes.
SETTING
a private ophthalmology clinic.
DESIGN
Prospective interventional case series.
METHODS
This prospective interventional case series enrolled 22 eyes of 22 patients who underwent femto-LASIK for the management of post-penetrating keratoplasty ametropia. The refractive error, uncorrected (UDVA), and corrected (CDVA) distance visual acuities and vector analysis were reported in short-term and long-term period after surgery.
RESULTS
The mean age was 32.7 ± 7.5 years (range, 23 to 47 years) at the surgery time. The average time between PK and femto-LASIK was 42.5 ± 31.7 months. The average follow-up duration after femto-LASIK was 81.2 ± 18.6 months. The mean preoperative UDVA significantly improved from 0.47 ± 0.15 logMAR to 0.35 ± 0.14 logMAR at 12 months (P = 0.048) and 0.4 ± 0.17 at final follow-up exam (P = 0.007). CDVA was 0.22 ± 0.1 at baseline which improved to 0.18 ± 0.15 and 0.15 ± 0.1 logMAR at 12 and 81 months, respectively. (Ps = 0.027, 0.014). The mean cylinder before surgery was - 5.04 ± 1.4D which significantly decreased to -1.5 ± 0.8 D at 12 months postoperatively. (P < 0.001). There was a significant increase in refractive astigmatism from 12 months to 81 months postoperatively (-3.1 ± 2.0, P = 0.002). At the final visit, the efficacy index was 0.83, and the safety index was 1.16.
CONCLUSIONS
Despite the short-term outcome indicated that femo-LASIK was effective for correction of post-keratoplasty ametropia during short-term period, a notable regression in its effect was observed in the long-term follow-up. Therefore, the predictability of this technique might decrease in the long-term.

Observational Study
PURPOSE
This study evaluates the recent trends in ocular morbidities and vision-related practices in "out-of-school" children in urban slums of Gurugram in North India.
METHODS
In this observational study, a validated questionnaire was administered to 161 students from two nonformal slum schools. Sociocultural, demographic data, vision-related practices, and visual acuity with subjective refraction of the children were recorded.
RESULTS
A total of 80 boys and 81 girls (9.17 ± 2.58 years) participated in this study. About 40% of the children were from lower socioeconomic status. The visual acuity recorded for all the children, except three children, was 6/6 in both eyes. One child had a pre-phthisical eye with no light perception, following a childhood trauma, with the other eye having 6/6 vision. Two children had refractive errors (myopia and compound myopic astigmatism), with a best corrected visual acuity (BCVA) of 6/6. Thirteen children (8%) had Bitot's spots and 67 (35.4%) had allergic conjunctivitis. Eight (5%) children complained of dry eye-related symptoms like redness and watering of eyes, while 19 (11.8%) had diffuse headache. Average number of years spent in school for these children was less than 1.7 years (range: 1 month-6 years). Only 10.5% of the children gave the history of watching television more than 30 h/week. Significant association was found between the income of father and use of digital devices in children below 10 years ( P = 0.003) and children playing outdoors ( P = 0.001). There was a significant association noted for age and use of digital devices ( P = 0.037).
CONCLUSION
The prevalence of refractive errors in "out-of-school" children of urban slum was much less than the national average. Almost one in three children suffered from eye allergies, while 8% children had Bitot's spots. The data about the prevalence of ocular comorbidities in underserved areas like urban slums can be used to update and strategize eye health-care delivery models for out-of-school children.

Translational Vision Science &... Apr 2024The purpose of this study was to explore risk factors for symptomatic presbyopia, defined as near add power ≥1.50 diopters, in patients with glaucoma.
PURPOSE
The purpose of this study was to explore risk factors for symptomatic presbyopia, defined as near add power ≥1.50 diopters, in patients with glaucoma.
METHODS
Treated glaucoma (n = 56), untreated glaucoma (n = 21), and control individuals (n = 376), aged 40 to 55 years at first visit, were enrolled in the study, and near add power, retinal thickness, and visual field were examined. The association between near add power and ocular parameters and the odds ratios (ORs) for symptomatic presbyopia were investigated. Survival analysis for symptomatic presbyopia was conducted.
RESULTS
Age, astigmatic power, mean deviation, and ganglion cell complex thickness were associated with near add power. The OR for symptomatic presbyopia was significant for age (OR = 1.51), astigmatism (OR = 1.01), mean deviation (OR = 0.72), ganglion cell complex thickness (OR = 0.98), treated and untreated glaucoma (OR = 2.09), and use of glaucoma eye drops (OR = 3.33). Survival analysis showed that the treated glaucoma group reached the near add power endpoint of ≥1.50 D (symptomatic presbyopia) significantly earlier than the other two groups, and there was no difference between the control and untreated glaucoma groups.
CONCLUSIONS
Glaucoma patients treated with eye drops may start near correction earlier.
TRANSLATIONAL RELEVANCE
Symptomatic presbyopia may develop earlier in patients with glaucoma, and our findings could further contribute to better management and understanding of presbyopia with glaucoma.

PURPOSE
Low doses of systemic doxycycline (LD-SD) inhibit angiogenesis and the expression of matrix metalloproteases, which are determinants of pterygium progression. This study aimed to compare the recurrence rate and visual outcome of pterygium excision in patients undergoing chronic treatment with LD-SD for chronic refractory blepharitis and LD-SD-naive patients.
METHODS
A retrospective analysis of patients that underwent surgical excision and conjunctival graft apposition was conducted. Patients were divided in a TETRA group (under LD-SD treatment at the moment of surgery) and a control group. The main outcome was the rate of recurrence at 1 year postoperatively. Secondary outcomes were the comparisons of surface regularity, visual quality, and dry-eye symptoms at 6-week, 6-month, and 1-year follow-up in the two groups.
RESULTS
The TETRA group showed a significantly lower rate of 1-year recurrence both in primary ( = 0.034) and recurrent ( < 0.001) pterygia. The best corrected visual acuity (BCVA), astigmatic error, corneal total root mean square (RMS), and ocular surface disease index (OSDI) significantly reduced during the follow-up in both groups. The surface asymmetry index and high-order aberrations (HOAs) significantly reduced only in the TETRA group. The final BCVA was significantly higher, while the OSDI score and total RMS and HOAs were significantly lower in the TETRA group compared to the control.
CONCLUSIONS
Patients under treatment with LD-SD showed a lower rate of recurrence at 1-year follow-up compared to controls. These patients also experienced higher BCVA and surface regularity and less dry-eye symptoms.
