“…In our study population, the spherical equivalent was already stable on the second post-operative day. Previous studies have reported stable spherical equivalent after 1 week and a significant refractory shift between the first post-operative day and 1 week after surgery [ 2 , 5 , 8 ]. Thus, our results suggest that the spherical equivalent stabilises sooner after uneventful cataract surgery than previously reported in many patients.…”

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.

“…In a subsequent analysis using 186 patients who underwent cataract surgery with Akreos Adapt AO IOL, we found a similar overall result that group D showed a reduced MAE2 (MAE based on the second examination) compared to MAE1 although it did not reach statistical significance, which might be related to small sample numbers (data not shown). Fifth, although previous literature reported that postoperative refraction stabilizes between 1 and 4 weeks following uneventful surgery, the refractive outcome measured at 1-month postoperatively may not be stable, requiring longer-term follow-up [27][28][29][30][31] .…”

This study aimed to determine whether inter-ocular differences in axial length (AL), corneal power (K), and adjusted emmetropic intraocular lens power (EIOLP) and inter-visit differences in these ocular biometric values, measured on different days, are related to refractive outcomes after cataract surgery. We retrospectively reviewed 279 patients who underwent phacoemulsification. Patients underwent ocular biometry twice (1–4 weeks before and on the day of surgery). Patients were divided into three groups: group S (similar inter-ocular biometry in different measurements; n = 201), group P (inter-ocular differences persisted in the second measurement; n = 37), and group D (inter-ocular difference diminished in the second measurement; n = 41). Postoperative refractive outcomes (mean absolute errors [MAEs]) were compared among the groups. Postoperative MAE2, based on second measurement with reduced inter-ocular biometry difference, was smaller than that calculated using the first measurement (MAE1) with borderline significance in group D (MAE1, 0.49 ± 0.45 diopters vs. MAE2, 0.41 ± 0.33 diopters, p = 0.062). Postoperative MAE2 was greater in group P compared to the other two groups (p = 0.034). Large inter-ocular biometry differences were associated with poor refractive outcomes after cataract surgery. These results indicate that measurements with smaller inter-ocular differences were associated with better refractive outcomes in cases with inter-visit biometry differences.

“…Oshika and Tsuboi reported that while refraction did not stabilise for more than three months following surgery using an 11 mm incision, refraction stabilised within two weeks when a 3.2 mm incision was used . This timeframe is supported by recent studies that report refractive stability can be achieved within one to two weeks when minimally invasive techniques are utilised …”

“…Although this study utilised spherical equivalent refraction which cannot distinguish between spherical and astigmatic error, the results show that both subjective and automated spherical equivalent refractive error remain stable from two weeks following surgery when minimally invasive surgical techniques are used (Figure ). Similar findings of stable refraction within shorter time periods following surgery have been reported in the literature by a number of other studies including Sugar et al and Caglar et al However, little literature is available regarding stabilisation times in the Australian context.…”

Background: Quality of life may be negatively impacted following cataract surgery if glasses prescription is delayed. This study aims to confirm the refractive stabilisation time in an Australian population to form the basis for suggesting an appropriate timeframe for spectacle prescription. Methods: Participants (51 female and 35 male) were recruited one day after uncomplicated unilateral cataract surgery using a monofocal intraocular lens. Subjective refraction, automated refraction and central corneal thickness were measured at two, four and six weeks post-operatively. A short questionnaire assessing the impact of uncorrected near vision on daily activities was collected at two and four weeks. Results: There was no significant change in the mean automated or subjective spherical equivalent refraction (p eq < 0.001), mean corneal thickness (p eq < 0.001), mean uncorrected distance visual acuity (p eq < 0.001) or mean uncorrected near visual acuity (p eq < 0.001) over the six-week study period. At week two, 59 per cent of patients stated that their uncorrected near vision affected their ability to perform daily tasks 'somewhat' or 'a lot', increasing to 75 per cent by week four. Conclusion: Uncorrected near vision affected quality of life for most participants. All measured visual and ocular parameters were stable from two weeks post-operatively. Patients need not wait longer than this for spectacle prescription following uncomplicated unilateral cataract surgery.
