“…There is no international consensus about the optimal timing to prescribe spectacles after cataract surgery. In Denmark, typical clinical practice suggests postponing new spectacles for at least 4 weeks, but is dependent on the clinician’s discretion [ 2 ]. In the past decade, progress has been made in cataract operation techniques and equipment.…”

Introduction: To determine which day automated refraction stabilised the first week after uneventful cataract surgery. Methods: This was a prospective, single-blinded, randomised cohort study of 148 eyes in 148 consecutive patients undergoing uneventful cataract surgery. Automated refraction was measured from days 2 to 7 after surgery and compared to automated refraction measured 6 weeks post-surgery. We compared measurements using a hierarchical mixed-effect model. Results: Our adjusted results did not show a statistically significant change in spherical equivalent between the first week after surgery and 6 weeks after surgery (p-values: day 2: 0.914, day 3: 0.922, day 4: 0.168, day 5: 0.211, day 6: 0.457, day 7: 0.621). We measured the spherical error as stable except for day 5, where a statistically significant change of 0.32 dioptre (p = 0.049) was detected. Similarly, the cylindrical error was also stable on all days of measurements except on day 6, where a significant change of 0.28 dioptre (p = 0.034) was detected. Conclusion:The adjusted spherical equivalent was stable on days 2-7 after uneventful cataract surgery in our study population. However, as we observed a statistically significant difference in spherical and cylindrical errors on days 5 and 6, respectively, we could not conclude that automated refraction stabilised the first week after uncomplicated cataract surgery.

“…Despite the substantial change in refraction and the resulting variation of accommodative demand, the bibliographic references regarding accommodation or binocularity status in highly ametropic patients implanted with phakic IOLs are scarce, but some authors reported that sphere‐ and spherical‐equivalent‐stability was achieved 1 month after surgery (Ostri et al. ).…”

To review binocular and accommodative disorders documented after corneal or intraocular refractive surgery, in normal healthy prepresbyopic patients. A bibliographic revision was performed; it included works published before 1st July 2017 where accommodation and/or binocularity was assessed following any type of refractive surgical procedure. The search in Pubmed yielded 1273 papers, 95 of which fulfilled the inclusion criteria. Few publications reporting binocular vision and/or accommodative changes after refractive surgery in normal subjects were found. The reduction in fusional vergence is the most frequently reported alteration. Anisometropia is an important risk factor for postoperative binocular vision-related complaints. Most diplopia-related visual complaints, irrespective of the surgical procedure, were in fact misdiagnosed preoperative disorders. The preoperative evaluation of patients seeking spectacle/contact lens independence should include a complete binocular and accommodation assessment where parameters such as the phoric posture, accommodative amplitude and facility, near point of convergence, fusional reserves and accommodative convergence/accommodation coefficient are measured. This would allow the identification of risk factors that could compromise the success of the refractive surgery and cause clinical symptoms.

“…They concluded spectacles could be prescribed 2-weeks following uneventful cataract surgery. The remaining three studies 27,28,32 concluded refraction was stable after 1-week. De Juan grouped together mean and SD using data from both eyes of most patients, 22 without correction for the lack of independence of right and left eye data.…”

Purpose We systematically reviewed the literature to investigate when refraction is stable following routine cataract surgery implanting monofocal intraocular lenses. Current advice recommends obtaining new spectacles 4–6 weeks following surgery. Due to advancements in surgical techniques, we hypothesised that refractive stability would be achieved earlier, which could have major short‐term improvements in quality of life for patients. Methods Medline, CINAHL, AMED, Embase, Web of Science and the Cochrane Library were searched with key words chosen to find articles, which assessed refraction following uncomplicated cataract surgery. Citation chains and the reference lists of all included papers were searched. Unpublished literature was identified using OpenGrey (http://www.opengrey.eu). The review considered studies that measured refraction at regular intervals following surgery until stability was achieved. Results The search identified 6,680 papers. Two reviewers independently screened the abstracts and nine papers were found to fit the criteria, of which five were included in the meta‐analysis. The quality of the papers was evaluated using the Methodological Index for Non‐Randomised Studies (MINORS) instrument. Meta‐analysis of 301 patients’ data of spherical, cylindrical and spherical equivalent correction were performed using Review Manager 5 (RevMan 5.3) (https://revman.cochrane.org/). Refraction at 1‐week versus the gold standard of 4‐weeks showed no significant difference for sphere data (effect size and 95% confidence interval of; ES = 0.00, 95% CI: −0.17, 0.17; p = 1.00), cylindrical data (ES = +0.06; 95% CI: −0.05, 0.17; p = 0.31), and spherical equivalent (ES = −0.01; 95% CI: −0.12, 0.10; p = 0.90). Heterogeneity was non‐significant (I2 < 25%) for all refractive elements. Data were similar for 2‐ versus 4‐weeks post‐surgery. Acquired data from one study highlighted a small number of patients with very unstable cylindrical corrections at 1‐week post‐operatively. Conclusions No statistical difference was found when comparing sphere, cylindrical and spherical equivalent values at 1‐ and 4‐weeks post cataract surgery. This suggests that new glasses could be provided 1‐week after surgery. However, from a clinical perspective, a small number of patients (~7%) from an acquired dataset (N = 72) showed very unstable cylindrical corrections at 1‐week. Further work is needed to determine why this is the case and how these patients can be detected.

Automated refraction is stable 1 week after uncomplicated cataract surgery

Abstract: Automated refraction is stabile 1 week after uncomplicated cataract surgery, but there is a trend towards instability, if the refractive target is missed with 1.0 D or more.
