“…Eyes of women who became pregnant after PRK have experienced refractive regression and corneal haze [45]. Changes in visual acuity and spherical equivalent have been reported in eyes of women who became pregnant after LASIK [46]. Although pregnancy normally precludes corneal laser surgery [47], sometimes an early stage pregnancy has inadvertently not been identified.…”

Plasminogen activator activity in tears of pregnant women

PurposePlasminogen activator activity (PAA) in tears of pregnant women was investigated at various gestation times to assess the availability of plasminogen activator for aiding potential corneal wound healing processes during pregnancy.MethodsPAA was measured by a spectrophotometric method. The analysis used 91 tear samples from pregnant and non-pregnant women, supplemented with 10 additional tear PAA measurements from non-pregnant women obtained in a previous study.ResultsTear levels of PAA in pregnant women formed a bimodal distribution. Either the tear PAA level was zero or non-zero during pregnancy. When non-zero, the tear PAA level was dissociated from gestation time and not different than non-pregnant and post-pregnant levels. The frequency of occurrence of zero level tear PAA increased with gestation: 16%, 17% and 46% had zero tear PAA in samples taken from women in the first, second and third trimester, respectively.ConclusionsOverall, of the tear samples taken from women during pregnancy, a total of 26% were at zero tear PAA. The remaining tear samples had non-zero tear PAA values throughout gestation equivalent to non-pregnant tear PAA values, suggesting local control of the source of PAA in tears. Given the importance of the plasminogen activator system in tears to wound healing in the cornea, and the high occurrence of zero tear PAA in our sample of pregnant women, elective corneal surgery would be contraindicated. If corneal surgery is nevertheless necessary, the tear PAA level would be worth checking and patients with low level should be closely observed during the postoperative period.

“…16,24,26 In summary, only 3 studies were in favor, whereas the other 7 studies were against refractive surgery procedures on pregnant or breastfeeding patients. 16,20,21,[23][24][25][26][27][28][29] Finally, the studies were grouped into 3 degrees, based on the risk of bias assessment tool: low evidence (yeses = 0 to 2); medium evidence (yeses = 3 to 5); and high evidence (yeses = 6 to 7). Ocular changes associated with pregnancy, such as the variation in tear production, intraocular pressure, and corneal and lens topographic alterations have been studied with inconclusive results in recent years.…”

“…31 However, these changes usually reverse after delivery or lactation, and some authors have proposed that these changes do not involve significant variations in visual acuity or refractive error during pregnancy. 29,32 The effect of pregnancy on the progression of myopia has been studied in a recent publication. 1 A cohort of 10 401 women aged between 20 and 50 years was prospectively evaluated since 1999.…”

“…Right eye dominance has been found to be more prevalent than left eye dominance [ 47 ]; therefore, it is possible that significantly more patients are receiving LASIK retreatments on the right eye as they are more likely to be right eye dominant, thus noticing more subtle changes in their vision. Lopez-Prats et al compared patients who had undergone LASIK before becoming pregnant to patients with non-surgically corrected eyes who had become pregnant [ 48 ]. They found significantly worsening cylinder and SE in patients with a history of LASIK, and they attributed this to the hormonal changes that occur during gestation.…”

Background: To evaluate the safety, efficacy, and predictability of laser-assisted in situ keratomileusis (LASIK) enhancement after primary LASIK and compare to Food and Drug Administration (FDA) criteria. Methods: Patients who underwent LASIK enhancement after primary LASIK between 2002 and 2019 were compared to those who underwent LASIK without retreatment. Patient demographics, preoperative characteristics, visual outcomes, and postoperative complications were compared between groups. Epithelial ingrowth (EI) development was stratified based on duration between primary and secondary procedures. Results: We compared 901 eyes with LASIK enhancement to 1127 eyes without retreatment. Age, sex, surgical eye, sphere, cylinder, and spherical equivalent (SE) were significantly different between groups (p < 0.05). At 12 months post-enhancement, 86% of the eyes had an uncorrected distance visual acuity of 20/20 or better and 93% of eyes were within ±0.50 D of the target. Development of EI (6.1%) demonstrated an odds ratio of 16.3 in the long-term compared to the short-term (95% CI: 5.9 to 45.18; p < 0.0001). Conclusions: Older age at primary LASIK, female sex, right eye, and larger sphere, cylinder and SE were risk factors for enhancement. Risk of EI significantly increased when duration between primary and enhancement procedures exceeded five years. LASIK enhancements produce favorable outcomes and meet FDA benchmarks for safety, efficacy, and predictability.
